It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if +you distribute copies of the library, or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link a program with the library, you must provide +complete object files to the recipients so that they can relink them +with the library, after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + c) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + d) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

Using SDL with Microsoft Visual C++ 5 and 6

+ +

+ by Lion Kimbro +

+ + + +

+ You can either use the precompiled libraries from + + the SDL Download web site , + or you can build SDL yourself. +

+ + +

Building SDL

+ +

+ Unzip the VisualC.zip file into the directory + that contains this file (VisualC.html). +

+ +

+ Be certain that you unzip VisualC.zip + into this directory and not any other + directory. If you are using WinZip, be careful to + make sure that it extracts to this + folder, because it's convenient feature of + unzipping to a folder with the name of the + file currently being unzipped will get you in + trouble if you use it right now. And that's all + I have to say about that. +

+ +

+ Now that it's unzipped, go into the VisualC directory + that is created, and double-click on the VC++ + workspace file "SDL.dsw". + This should open up VisualC. +

+ +

+ You may be prompted at this point to upgrade the + workspace, should you be using a more recent version + of Visual C++. If so, allow the workspace to be + upgraded. +

+ + +

+ Build the .dll and .lib files. +

+ +

+ This is done by right clicking on each project in turn + (Projects are listed in the Workspace panel in the + FileView tab), and selecting "Build". +

+ +

+ You may get a few warnings, but you should not get + any errors. You do have to have at least the DirectX + 5 SDK installed, however. (I believe...) The latest + version of DirectX can be downloaded or purchased + on a cheap CD (my recommendation) from + Microsoft . +

+ +

+ Later, we will refer to the following .lib and .dll + files that have just been generated: +

+ + +
  • SDL.dll +
  • SDL.lib +
  • SDLmain.lib + + +

    + Search for these using the Windows Find (Windows-F) + utility, if you don't already know where they should be. + For those of you with a clue, look inside the Debug + or Release directories of the subdirectories of the + VisualC folder. (It might be easier to just use + Windows Find if this sounds confusing. And don't worry + about needing a clue; we all need visits from the + clue fairy frequently.) +

    + + + +

    Creating a Project with SDL

    + +

    + Create a project as a Win32 Application. +

    + +

    + Create a C++ file for your project. +

    + +

    + Set the C runtime to "Multi-threaded DLL" in the menu: + Project|Settings|C/C++ tab|Code Generation|Runtime Library . +

    + +

    + Add the SDL include directory to your list + of includes in the menu: + Project|Settings|C/C++ tab|Preprocessor|Additional include directories . +

    + +

    + The "include directory" I am referring to is the + include folder within the main SDL + directory (the one that this HTML file located + within. +

    + +

    + Now we're going to use the files that we had created + earlier in the Build SDL step. +

    + +

    + Copy the following files into your Project directory: +

    + + +
  • SDL.dll
    • +     + +

    + Copy the following files into your Project directory, + and add them to your Project as well: +

    + + +
  • SDL.lib
    • +
  • SDLmain.lib
    • +     + +

    + (To add them to your project, right click on your + project, and select "Add files to project") +

    + +

    + (I believe that it's not necessary to actually + copy the .lib files into your directory; you only + have to be certain that you add them to your Project. + If someone is so inclined, correct this document, or + + e-mail me , + and I'll fix this document.) +

    + + + +

    SDL 101, First Day of Class

    + +

    + Now create the basic body of your project. + The body of your program should take the following form: + + +

    +#include "SDL.h"
+
+int main( int argc, char* argv[] )
+{
+  // Body of the program goes here.
+  return 0;
+}
+
    + +

    + +

    That's it!

    + +

    + I hope that this document has helped you get + through the most difficult part of using the + SDL: installing it. Suggestions for improvements + to this document should be sent to the writers + of this document. +

    + +

    + Thanks to Paulus Esterhazy (pesterhazy@gmx.net), for the work on VC++ port. +

    + +

    + This document was originally called "VisualC.txt", + and was written by + Sam Lantinga. +

For an example of + implementing gamma correction and gamma fades, see test/testgamma.c + Gamma control is not supported on all hardware. + +1.1.4: + The size of the SDL_CDtrack structure changed from 8 to 12 bytes + as the size of the length member was extended to 32 bits. + + You can now use SDL for 2D blitting with a GL mode by passing the + SDL_OPENGLBLIT flag to SDL_SetVideoMode().

Color cursors should + be implemented as sprites, blitted by the application when the + cursor moves. To get smooth color cursor updates when the app + is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init(). This + allows you to handle the mouse motion in another thread from an + event filter function, but is currently only supported by Linux + and BeOS. Note that you'll have to protect the display surface + from multi-threaded access by using mutexes if you do this. + + Thread-safe surface support has been removed from SDL. + This makes blitting somewhat faster, by removing SDL_MiddleBlit(). + Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead. + You can make your surfaces thread-safe by allocating your own + mutex and making lock/unlock calls around accesses to your surface. + +0.9.14: + SDL_GetMouseState() now takes pointers to int rather than Uint16. + + If you set the SDL_WINDOWID environment variable under UNIX X11, + SDL will use that as the main window instead of creating it's own. + This is an unsupported extension to SDL, and not portable at all. + +0.9.13: + Added a function SDL_SetLibraryPath() which can be used to specify + the directory containing the SDL dynamic libraries. This is useful + for commercial applications which ship with particular versions + of the libraries, and for security on multi-user systems. + If this function is not used, the default system directories are + searched using the native dynamic object loading mechanism. + + In order to support C linkage under Visual C++, you must declare + main() without any return type: + main(int argc, char *argv[]) { + /* Do the program... */ + return(0); + } + C++ programs should also return a value if compiled under VC++. + + The blit_endian member of the SDL_VideoInfo struct has been removed. + + SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there + is now no longer any function to translate a keysym to a character. + + The SDL_keysym structure has been extended with a 'scancode' and + 'unicode' member. The 'scancode' is a hardware specific scancode + for the key that was pressed, and may be 0. The 'unicode' member + is a 16-bit UNICODE translation of the key that was pressed along + with any modifiers or compose keys that have been pressed. + If no UNICODE translation exists for the key, 'unicode' will be 0. + + Added a function SDL_EnableUNICODE() to enable/disable UNICODE + translation of character keypresses. Translation defaults off. + + To convert existing code to use the new API, change code which + uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(), + and change code which uses it to get the ASCII value of a sym to + use the 'unicode' member of the event keysym. + +0.9.12: + There is partial support for 64-bit datatypes. I don't recommend + you use this if you have a choice, because 64-bit datatypes are not + supported on many platforms. On platforms for which it is supported, + the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and + you can use the Uint64 and Sint64 datatypes. + + Added functions to SDL_endian.h to support 64-bit datatypes: + SDL_SwapLE64(), SDL_SwapBE64(), + SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64() + + A new member "len_ratio" has been added to the SDL_AudioCVT structure, + and allows you to determine either the original buffer length or the + converted buffer length, given the other. + + A new function SDL_FreeWAV() has been added to the API to free data + allocated by SDL_LoadWAV_RW(). This is necessary under Win32 since + the gcc compiled DLL uses a different heap than VC++ compiled apps. + + SDL now has initial support for international keyboards using the + Latin character set. + If a particular mapping is desired, you can set the DEFAULT_KEYBOARD + compile-time variable, or you can set the environment variable + "SDL_KEYBOARD" to a string identifying the keyboard mapping you desire. + The valid values for these variables can be found in SDL_keyboard.c + + Full support for German and French keyboards under X11 is implemented. + +0.9.11: + The THREADED_EVENTS compile-time define has been replaced with the + SDL_INIT_EVENTTHREAD flag. If this flag is passed to SDL_Init(), + SDL will create a separate thread to perform input event handling. + If this flag is passed to SDL_Init(), and the OS doesn't support + event handling in a separate thread, SDL_Init() will fail. + Be sure to add calls to SDL_Delay() in your main thread to allow + the OS to schedule your event thread, or it may starve, leading + to slow event delivery and/or dropped events. + Currently MacOS and Win32 do not support this flag, while BeOS + and Linux do support it. I recommend that your application only + use this flag if absolutely necessary. + + The SDL thread function passed to SDL_CreateThread() now returns a + status. This status can be retrieved by passing a non-NULL pointer + as the 'status' argument to SDL_WaitThread(). + + The volume parameter to SDL_MixAudio() has been increased in range + from (0-8) to (0-128) + + SDL now has a data source abstraction which can encompass a file, + an area of memory, or any custom object you can envision. It uses + these abstractions, SDL_RWops, in the endian read/write functions, + and the built-in WAV and BMP file loaders. This means you can load + WAV chunks from memory mapped files, compressed archives, network + pipes, or anything else that has a data read abstraction. + + There are three built-in data source abstractions: + SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem() + along with a generic data source allocation function: + SDL_AllocRW() + These data sources can be used like stdio file pointers with the + following convenience functions: + SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose() + These functions are defined in the new header file "SDL_rwops.h" + + The endian swapping functions have been turned into macros for speed + and SDL_CalculateEndian() has been removed. SDL_endian.h now defines + SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on + the endianness of the host system. + + The endian read/write functions now take an SDL_RWops pointer + instead of a stdio FILE pointer, to support the new data source + abstraction. + + The SDL_*LoadWAV() functions have been replaced with a single + SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's + first parameter, and a flag whether or not to automatically + free it as the second parameter. SDL_LoadWAV() is a macro for + backward compatibility and convenience: + SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...); + + The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced + with a single function that takes a SDL_RWops pointer as it's + first parameter, and a flag whether or not to automatically + free it as the second parameter. SDL_LoadBMP() and SDL_SaveBMP() + are macros for backward compatibility and convenience: + SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...); + SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...); + Note that these functions use SDL_RWseek() extensively, and should + not be used on pipes or other non-seekable data sources. + +0.9.10: + The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been + extended to support multiple types of display drivers, as well as + safe access to the X11 display when THREADED_EVENTS is enabled. + The new structures are documented in the SDL_syswm.h header file. + + Thanks to John Elliott , the UK keyboard + should now work properly, as well as the "Windows" keys on US + keyboards. + + The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab + instead of trying to open each block device on the system. + The CD must be listed in /etc/fstab as using the iso9660 filesystem. + + On Linux, if you define THREADED_EVENTS at compile time, a separate + thread will be spawned to gather X events asynchronously from the + graphics updates. This hasn't been extensively tested, but it does + provide a means of handling keyboard and mouse input in a separate + thread from the graphics thread. (This is now enabled by default.) + + A special access function SDL_PeepEvents() allows you to manipulate + the event queue in a thread-safe manner, including peeking at events, + removing events of a specified type, and adding new events of arbitrary + type to the queue (use the new 'user' member of the SDL_Event type). + + If you use SDL_PeepEvents() to gather events, then the main graphics + thread needs to call SDL_PumpEvents() periodically to drive the event + loop and generate input events. This is not necessary if SDL has been + compiled with THREADED_EVENTS defined, but doesn't hurt. + + A new function SDL_ThreadID() returns the identifier associated with + the current thread. + +0.9.9: + The AUDIO_STEREO format flag has been replaced with a new 'channels' + member of the SDL_AudioSpec structure. The channels are 1 for mono + audio, and 2 for stereo audio. In the future more channels may be + supported for 3D surround sound. + + The SDL_MixAudio() function now takes an additional volume parameter, + which should be set to SDL_MIX_MAXVOLUME for compatibility with the + original function. + + The CD-ROM functions which take a 'cdrom' parameter can now be + passed NULL, and will act on the last successfully opened CD-ROM. + +0.9.8: + No changes, bugfixes only. + +0.9.7: + No changes, bugfixes only. + +0.9.6: + Added a fast rectangle fill function: SDL_FillRect() + + Addition of a useful function for getting info on the video hardware: + const SDL_VideoInfo *SDL_GetVideoInfo(void) + This function replaces SDL_GetDisplayFormat(). + + Initial support for double-buffering: + Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode() + Update the screen with a new function: SDL_Flip() + + SDL_AllocSurface() takes two new flags: + SDL_SRCCOLORKEY means that the surface will be used for colorkey blits + and if the hardware supports hardware acceleration of colorkey blits + between two surfaces in video memory, to place the surface in video + memory if possible, otherwise it will be placed in system memory. + SDL_SRCALPHA means that the surface will be used for alpha blits and + if the hardware supports hardware acceleration of alpha blits between + two surfaces in video memory, to place the surface in video memory + if possible, otherwise it will be placed in system memory. + SDL_HWSURFACE now means that the surface will be created with the + same format as the display surface, since having surfaces in video + memory is only useful for fast blitting to the screen, and you can't + blit surfaces with different surface formats in video memory. + +0.9.5: + You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume + that the icon consists of the entire image. + + SDL_LowerBlit() is back -- but don't use it on the display surface. + It is exactly the same as SDL_MiddleBlit(), but doesn't check for + thread safety. + + Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take + a FILE pointer instead of a file name. + + Added CD-ROM audio control API: + SDL_CDNumDrives() + SDL_CDName() + SDL_CDOpen() + SDL_CDStatus() + SDL_CDPlayTracks() + SDL_CDPlay() + SDL_CDPause() + SDL_CDResume() + SDL_CDStop() + SDL_CDEject() + SDL_CDClose() + +0.9.4: + No changes, bugfixes only. + +0.9.3: + Mouse motion event now includes relative motion information: + Sint16 event->motion.xrel, Sint16 event->motion.yrel + + X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT + (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile) + +0.9.2: + No changes, bugfixes only. + +0.9.1: + Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now + automatically mapped on blit. + +0.8.0: + SDL stable release diff --git a/acinclude.m4 b/acinclude.m4 new file mode 100644 index 000000000..0670b2db9 --- /dev/null +++ b/acinclude.m4 @@ -0,0 +1,619 @@ +# Local macros for the SDL configure.in script + +dnl Function to link an architecture specific file +dnl LINK_ARCH_SRC(source_dir, arch, source_file) +AC_DEFUN(COPY_ARCH_SRC, +[ + echo "Copying $1/$2/$3 -> $1/$3" + old="$srcdir/$1/$2/$3" + new="$srcdir/$1/$3" + cat >$new <<__EOF__ +/* WARNING: This file was automatically generated!

    SDL_CloseAudio — Shuts down audio processing and closes the audio device.

    Sound on the computer is translated from waves that you hear into a series of +values, or samples, each representing the amplitude of the wave. When these +samples are sent in a stream to a sound card, an approximation of the original +wave can be recreated. The more bits used to represent the amplitude, and the +greater frequency these samples are gathered, the closer the approximated +sound is to the original, and the better the quality of sound.

    This library supports both 8 and 16 bit signed and unsigned sound samples, +at frequencies ranging from 11025 Hz to 44100 Hz, depending on the +underlying hardware. If the hardware doesn't support the desired audio +format or frequency, it can be emulated if desired (See +SDL_OpenAudio())

    A commonly supported audio format is 16 bits per sample at 22050 Hz.

    Chapter 11. CD-ROM

    Table of Contents
    SDL_CDNumDrives — Returns the number of CD-ROM drives on the system.
    SDL_CDName — Returns a human-readable, system-dependent identifier for the CD-ROM.
    SDL_CDOpen — Opens a CD-ROM drive for access.
    SDL_CDStatus — Returns the current status of the given drive.
    SDL_CDPlay — Play a CD
    SDL_CDPlayTracks — Play the given CD track(s)
    SDL_CDPause — Pauses a CDROM
    SDL_CDResume — Resumes a CDROM
    SDL_CDStop — Stops a CDROM
    SDL_CDEject — Ejects a CDROM
    SDL_CDClose — Closes a SDL_CD handle
    SDL_CD — CDROM Drive Information
    SDL_CDtrack — CD Track Information Structure

    SDL supports audio control of up to 32 local CD-ROM drives at once.

    You use this API to perform all the basic functions of a CD player, +including listing the tracks, playing, stopping, and ejecting the CD-ROM. +(Currently, multi-changer CD drives are not supported.)

    Before you call any of the SDL CD-ROM functions, you must first call +"SDL_Init(SDL_INIT_CDROM)", which scans the system for +CD-ROM drives, and sets the program up for audio control. Check the +return code, which should be 0, to see if there +were any errors in starting up.

    After you have initialized the library, you can find out how many drives +are available using the SDL_CDNumDrives() function. +The first drive listed is the system default CD-ROM drive. After you have +chosen a drive, and have opened it with SDL_CDOpen(), +you can check the status and start playing if there's a CD in the drive.

    A CD-ROM is organized into one or more tracks, each consisting of a certain +number of "frames". Each frame is ~2K in size, and at normal playing speed, +a CD plays 75 frames per second. SDL works with the number of frames on a +CD, but this can easily be converted to the more familiar minutes/seconds +format by using the FRAMES_TO_MSF() macro.

    Chapter 8. Events

    Introduction

    Event handling allows your application to receive input from the user. Event handling is initalised (along with video) with a call to: +

    SDL_Init(SDL_INIT_VIDEO);
    +Interally, SDL stores all the events waiting to be handled in an event queue. Using functions like SDL_PollEvent and SDL_PeepEvents you can observe and handle waiting input events.

    The key to event handling in SDL is the SDL_Event union. The event queue itself is composed of a series of SDL_Event unions, one for each waiting event. SDL_Event unions are read from the queue with the SDL_PollEvent function and it is then up to the application to process the information stored with them.

    SDL_Init — Initializes SDL
    SDL_InitSubSystem — Initialize subsystems
    SDL_QuitSubSystem — Shut down a subsystem
    SDL_Quit — Shut down SDL
    SDL_WasInit — Check which subsystems are initialized

    Before SDL can be used in a program it must be initialized with SDL_Init. SDL_Init initializes all the subsystems that the user requests (video, audio, joystick, timers and/or cdrom). Once SDL is initialized with SDL_Init subsystems can be shut down and initialized as needed using SDL_InitSubSystem and SDL_QuitSubSystem.

    SDL must also be shut down before the program exits to make sure it cleans up correctly. Calling SDL_Quit shuts down all subsystems and frees any resources allocated to SDL.

    Initializing SDL

    SDL is composed of eight subsystems - Audio, CDROM, Event Handling, File I/O, Joystick Handling, Threading, Timers and Video. Before you can use any of these subsystems they must be initialized by calling SDL_Init (or SDL_InitSubSystem. SDL_Init must be called before any other SDL function. It automatically initializes the Event Handling, File I/O and Threading subsystems and it takes a parameter specifying which other subsystems to initialize. So, to initialize the default subsystems and the Video subsystems you would call: +

        SDL_Init ( SDL_INIT_VIDEO );
    +To initialize the default subsystems, the Video subsystem and the Timers subsystem you would call: +
        SDL_Init ( SDL_INIT_VIDEO | SDL_INIT_TIMER );

    SDL_Init is complemented by SDL_Quit (and SDL_QuitSubSystem). SDL_Quit shuts down all subsystems, including the default ones. It should always be called before a SDL application exits.

    With SDL_Init and SDL_Quit firmly embedded in your programmers toolkit you can write your first and most basic SDL application. However, we must be prepare to handle errors. Many SDL functions return a value and indicates whether the function has succeeded or failed, SDL_Init, for instance, returns -1 if it could not initialize a subsystem. SDL provides a useful facility that allows you to determine exactly what the problem was, every time an error occurs within SDL an error message is stored which can be retrieved using SDL_GetError. Use this often, you can never know too much about an error.

    #include "SDL.h"   /* All SDL App's need this */
+#include <stdio.h>
+
+int main() {
+    
+    printf("Initializing SDL.\n");
+    
+    /* Initialize defaults, Video and Audio */
+    if((SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO)==-1)) { 
+        printf("Could not initialize SDL: %s.\n", SDL_GetError());
+        exit(-1);
+    }
+
+    printf("SDL initialized.\n");
+
+    printf("Quiting SDL.\n");
+    
+    /* Shutdown all subsystems */
+    SDL_Quit();
+    
+    printf("Quiting....\n");
+
+    exit(0);

    Chapter 3. Input handling

    Handling Joysticks

    Initialization

    The first step in using a joystick in a SDL program is to initialize the Joystick subsystems of SDL. This done by passing the SDL_INIT_JOYSTICK flag to SDL_Init. The joystick flag will usually be used in conjunction with other flags (like the video flag) because the joystick is usually used to control something. +

        if ( ! SDL_Init( SDL_INIT_VIDEO | SDL_INIT_JOYSTICK ) )
+    {
+        fprintf(stderr, "Couldn't initialize SDL: %s\n", SDL_GetError());
+        exit(1);
+    }
    +This will attempt to start SDL with both the video and the joystick subsystems activated.

    Querying

    If we have reached this point then we can safely assume that the SDL library has been initialized and that the Joystick subsystem is active. We can now call some video and/or sound functions to get things going before we need the joystick. Eventually we have to make sure that there is actually a joystick to work with. It's wise to always check even if you know a joystick will be present on the system because it can also help detect when the joystick is unplugged. The function used to check for joysticks is SDL_NumJoysticks.

    This function simply returns the number of joysticks available on the system. If it is at least one then we are in good shape. The next step is to determine which joystick the user wants to use. If the number of joysticks available is only one then it is safe to assume that one joystick is the one the user wants to use. SDL has a function to get the name of the joysticks as assigned by the operations system and that function is SDL_JoystickName. The joystick is specified by an index where 0 is the first joystick and the last joystick is the number returned by SDL_NumJoysticks - 1. In the demonstration a list of all available joysticks is printed to stdout. +

        printf("%i joysticks were found.\n\n", SDL_NumJoysticks() );
+    printf("The names of the joysticks are:\n");
+		
+    for( i=0; i < SDL_NumJoysticks(); i++ ) 
+    {
+        printf("    %s\n", SDL_JoystickName(i));
+    }

    Opening a Joystick and Receiving Joystick Events

    SDL's event driven architecture makes working with joysticks a snap. Joysticks can trigger 4 different types of events: +

    SDL_JoyAxisEventOccurs when an axis changes
    SDL_JoyBallEventOccurs when a joystick trackball's position changes
    SDL_JoyHatEventOccurs when a hat's position changes
    SDL_JoyButtonEventOccurs when a button is pressed or released

    Events are received from all joysticks opened. The first thing that needs to be done in order to receive joystick events is to call SDL_JoystickEventState with the SDL_ENABLE flag. Next you must open the joysticks that you want to receive envents from. This is done with the SDL_JoystickOpen function. For the example we are only interested in events from the first joystick on the system, regardless of what it may be. To receive events from it we would do this: +

        SDL_Joystick *joystick;
+
+    SDL_JoystickEventState(SDL_ENABLE);
+    joystick = SDL_JoystickOpen(0);
    +If we wanted to receive events for other joysticks we would open them with calls to SDL_JoystickOpen just like we opened joystick 0, except we would store the SDL_Joystick structure they return in a different pointer. We only need the joystick pointer when we are querying the joysticks or when we are closing the joystick.

    Up to this point all the code we have is used just to initialize the joysticks in order to read values at run time. All we need now is an event loop, which is something that all SDL programs should have anyway to receive the systems quit events. We must now add code to check the event loop for at least some of the above mentioned events. Let's assume our event loop looks like this: +

        SDL_Event *event;
+    /* Other initializtion code goes here */   
+
+    /* Start main game loop here */
+
+    while(SDL_PollEvent(&event))
+    {  
+        switch(event.type)
+        {  
+            case SDL_KEYDOWN:
+            /* handle keyboard stuff here */				
+            break;
+
+            case SDL_QUIT:
+            /* Set whatever flags are necessary to */
+            /* end the main game loop here */
+            break;
+        }
+    }
+
+    /* End loop here */
    +To handle Joystick events we merely add cases for them, first we'll add axis handling code. Axis checks can get kinda of tricky because alot of the joystick events received are junk. Joystick axis have a tendency to vary just a little between polling due to the way they are designed. To compensate for this you have to set a threshold for changes and ignore the events that have'nt exceeded the threshold. 10% is usually a good threshold value. This sounds a lot more complicated than it is. Here is the Axis event handler: +
        case SDL_JOYAXISMOTION:  /* Handle Joystick Motion */
+    if ( ( event.jaxis.value < -3200 ) || (event.jaxis.value > 3200 ) ) 
+    {
+      /* code goes here */
+    }
+    break;
    +Another trick with axis events is that up-down and left-right movement are two different sets of axes. The most important axis is axis 0 (left-right) and axis 1 (up-down). To handle them seperatly in the code we do the following: +
        case SDL_JOYAXISMOTION:  /* Handle Joystick Motion */
+    if ( ( event.jaxis.value < -3200 ) || (event.jaxis.value > 3200 ) ) 
+    {
+        if( event.jaxis.axis == 0) 
+        {
+            /* Left-right movement code goes here */
+        }
+
+        if( event.jaxis.axis == 1) 
+        {
+            /* Up-Down movement code goes here */
+        }
+    }
+    break;
    +Ideally the code here should use event.jaxis.value to scale something. For example lets assume you are using the joystick to control the movement of a spaceship. If the user is using an analog joystick and they push the stick a little bit they expect to move less than if they pushed it a lot. Designing your code for this situation is preferred because it makes the experience for users of analog controls better and remains the same for users of digital controls.

    If your joystick has any additional axis then they may be used for other sticks or throttle controls and those axis return values too just with different event.jaxis.axis values.

    Button handling is simple compared to the axis checking. +

        case SDL_JOYBUTTONDOWN:  /* Handle Joystick Button Presses */
+    if ( event.jbutton.button == 0 ) 
+    {
+        /* code goes here */
+    }
+    break;
    + +Button checks are simpler than axis checks because a button can only be pressed or not pressed. The SDL_JOYBUTTONDOWN event is triggered when a button is pressed and the SDL_JOYBUTTONUP event is fired when a button is released. We do have to know what button was pressed though, that is done by reading the event.jbutton.button field.

    Lastly when we are through using our joysticks we should close them with a call to SDL_JoystickClose. To close our opened joystick 0 we would do this at the end of our program: +

        SDL_JoystickClose(joystick);

    Advanced Joystick Functions

    That takes care of the controls that you can count on being on every joystick under the sun, but there are a few extra things that SDL can support. Joyballs are next on our list, they are alot like axis we a few minor differences. Joyballs store relative changes unlike the the absolute postion stored in a axis event. Also one trackball event contains both the change in x and they change in y. Our case for it is as follows: +

        case SDL_JOYBALLMOTION:  /* Handle Joyball Motion */
+    if( event.jball.ball == 0 )
+    {
+      /* ball handling */
+    }
+    break;
    +The above checks the first joyball on the joystick. The change in position will be stored in event.jball.xrel and event.jball.yrel.

    Finally we have the hat event. Hats report only the direction they are pushed in. We check hat's position with the bitmasks: + +

    SDL_HAT_CENTERED
    SDL_HAT_UP
    SDL_HAT_RIGHT
    SDL_HAT_DOWN
    SDL_HAT_LEFT

    + +Also there are some predefined combinations of the above: +

    SDL_HAT_RIGHTUP
    SDL_HAT_RIGHTDOWN
    SDL_HAT_LEFTUP
    SDL_HAT_LEFTDOWN

    + +Our case for the hat may resemble the following: + +
        case SDL_JOYHATMOTION:  /* Handle Hat Motion */
+    if ( event.jhat.hat | SDL_HAT_UP )
+    {
+        /* Do up stuff here */
+    }
+
+    if ( event.jhat.hat | SDL_HAT_LEFT )
+    {
+        /* Do left stuff here */
+    }
+
+    if ( event.jhat.hat | SDL_HAT_RIGHTDOWN )
+    {
+        /* Do right and down together stuff here */
+    }
+    break;

    In addition to the queries for number of joysticks on the system and their names there are additional functions to query the capabilities of attached joysticks: +

    SDL_JoystickNumAxesReturns the number of joysitck axes
    SDL_JoystickNumButtonsReturns the number of joysitck buttons
    SDL_JoystickNumBallsReturns the number of joysitck balls
    SDL_JoystickNumHatsReturns the number of joysitck hats

    + +To use these functions we just have to pass in the joystick structure we got when we opened the joystick. For Example: + +
        int number_of_buttons;
+    SDL_Joystick *joystick;
+
+    joystick = SDL_JoystickOpen(0);
+    number_of_buttons = SDL_JoystickNumButtons(joystick);
    + +This block of code would get the number of buttons on the first joystick in the system.

    Handling the Keyboard

    Keyboard Related Structures

    It should make it a lot easier to understand this tutorial is you are familiar with the data types involved in keyboard access, so I'll explain them first.

    SDLKey

    SDLKey is an enumerated type defined in SDL/include/SDL_keysym.h and detailed here. Each SDLKey symbol represents a key, SDLK_a corresponds to the 'a' key on a keyboard, SDLK_SPACE corresponds to the space bar, and so on.

    SDLMod

    SDLMod is an enumerated type, similar to SDLKey, however it enumerates keyboard modifiers (Control, Alt, Shift). The full list of modifier symbols is here. SDLMod values can be AND'd together to represent several modifiers.

    SDL_keysym

    typedef struct{
+  Uint8 scancode;
+  SDLKey sym;
+  SDLMod mod;
+  Uint16 unicode;
+} SDL_keysym;

    The SDL_keysym structure describes a key press or a key release. The scancode field is hardware specific and should be ignored unless you know what your doing. The sym field is the SDLKey value of the key being pressed or released. The mod field describes the state of the keyboard modifiers at the time the key press or release occurred. So a value of KMOD_NUM | KMOD_CAPS | KMOD_LSHIFT would mean that Numlock, Capslock and the left shift key were all press (or enabled in the case of the lock keys). Finally, the unicode field stores the 16-bit unicode value of the key.

    Note: It should be noted and understood that this field is only valid when the SDL_keysym is describing a key press, not a key release. Unicode values only make sense on a key press because the unicode value describes an international character and only key presses produce characters. More information on Unicode can be found at www.unicode.org

    Note: Unicode translation must be enabled using the SDL_EnableUNICODE function.

    SDL_KeyboardEvent

    typedef struct{
+  Uint8 type;
+  Uint8 state;
+  SDL_keysym keysym;
+} SDL_KeyboardEvent;

    The SDL_KeyboardEvent describes a keyboard event (obviously). The key member of the SDL_Event union is a SDL_KeyboardEvent structure. The type field specifies whether the event is a key release (SDL_KEYUP) or a key press (SDL_KEYDOWN) event. The state is largely redundant, it reports the same information as the type field but uses different values (SDL_RELEASED and SDL_PRESSED). The keysym contains information of the key press or release that this event represents (see above).

    Reading Keyboard Events

    Reading keybaord events from the event queue is quite simple (the event queue and using it is described here). We read events using SDL_PollEvent in a while() loop and check for SDL_KEYUP and SDL_KEYDOWN events using a switch statement, like so: +

      SDL_Event event;
+  .
+  .
+  /* Poll for events. SDL_PollEvent() returns 0 when there are no  */
+  /* more events on the event queue, our while loop will exit when */
+  /* that occurs.                                                  */
+  while( SDL_PollEvent( &event ) ){
+    /* We are only worried about SDL_KEYDOWN and SDL_KEYUP events */
+    switch( event.type ){
+      case SDL_KEYDOWN:
+        printf( "Key press detected\n" );
+        break;
+
+      case SDL_KEYUP:
+        printf( "Key release detected\n" );
+        break;
+
+      default:
+        break;
+    }
+  }
+  .
+  .
    +This is a very basic example. No information about the key press or release is interpreted. We will explore the other extreme out our first full example below - reporting all available information about a keyboard event.

    A More Detailed Look

    Before we can read events SDL must be initialised with SDL_Init and a video mode must be set using SDL_SetVideoMode. There are, however, two other functions we must use to obtain all the information required. We must enable unicode translation by calling SDL_EnableUNICODE(1) and we must convert SDLKey values into something printable, using SDL_GetKeyName

    Note: It is useful to note that unicode values < 0x80 translate directly a characters ASCII value. THis is used in the example below

    Example 3-1. keys.c - Key event information

    
    #include "SDL.h"
+
+    /* Function Prototypes */
+    void PrintKeyInfo( SDL_KeyboardEvent *key );
+    void PrintModifiers( SDLMod mod );

+    /* main */
+    int main( int argc, char *argv[] ){
+        
+        SDL_Event event;
+        int quit = 0;
+        
+        /* Initialise SDL */
+        if( SDL_Init( SDL_INIT_VIDEO ) ){
+            fprintf( stderr, "Could not initialise SDL: %s\n", SDL_GetError() );
+            exit( -1 );
+        }
+
+        /* Set a video mode */
+        if( !SDL_SetVideoMode( 320, 200, 0, 0 ) ){
+            fprintf( stderr, "Could not set video mode: %s\n", SDL_GetError() );
+            SDL_Quit();
+            exit( -1 );
+        }
+
+        /* Enable Unicode translation */
+        SDL_EnableUNICODE( 1 );

+        while( !quit ){

+                    case SDL_QUIT:

+                        break;

+        }

    Game-type Input

    I have found that people using keyboard events for games and other interactive applications don't always understand one fundemental point.

    Keyboard events only take place when a keys state changes from being unpressed to pressed, and vice versa.

    Imagine you have an image of an alien that you wish to move around using the cursor keys - when you pressed the left arrow key you want him to slide over to the left, when you press the down key you want him to slide down the screen. Examine the following code, it highlights and error that many people have made. +

        /* Alien screen coordinates */
+    int alien_x=0, alien_y=0;
+    .
+    .
+    /* Initialise SDL and video modes and all that */
+    .
+    /* Main game loop */
+    /* Check for events */
+    while( SDL_PollEvent( &event ) ){
+        switch( event.type ){
+            /* Look for a keypress */
+            case SDL_KEYDOWN:
+                /* Check the SDLKey values and move change the coords */
+                switch( event.key.keysym.sym ){
+                    case SDLK_LEFT:
+                        alien_x -= 1;
+                        break;
+                    case SDLK_RIGHT:
+                        alien_x += 1;
+                        break;
+                    case SDLK_UP:
+                        alien_y -= 1;
+                        break;
+                    case SDLK_DOWN:
+                        alien_y += 1;
+                        break;
+                    default:
+                        break;
+                }
+            }
+        }
+    }
+    .
+    .
    +At first glance you may think this is a perfectly reasonable piece of code for the task, but it isn't. Like I said keyboard events only occur when a key changes state, so the user would have to press and release the left cursor key 100 times to move the alien 100 pixels to the left.

    To get around this problem we must not use the events to change the position of the alien, we use the events to set flags which are then used in a seperate section of code to move the alien. Something like this: +

        /* Alien screen coordinates */
+    int alien_x=0, alien_y=0;
+    int alien_xvel=0, alien_yvel=0;
+    .
+    .
+    /* Initialise SDL and video modes and all that */
+    .
+    /* Main game loop */
+    /* Check for events */
+    while( SDL_PollEvent( &event ) ){
+        switch( event.type ){
+            /* Look for a keypress */
+            case SDL_KEYDOWN:
+                /* Check the SDLKey values and move change the coords */
+                switch( event.key.keysym.sym ){
+                    case SDLK_LEFT:
+                        alien_xvel = -1;
+                        break;
+                    case SDLK_RIGHT:
+                        alien_xvel =  1;
+                        break;
+                    case SDLK_UP:
+                        alien_yvel = -1;
+                        break;
+                    case SDLK_DOWN:
+                        alien_yvel =  1;
+                        break;
+                    default:
+                        break;
+                }
+                break;
+            /* We must also use the SDL_KEYUP events to zero the x */
+            /* and y velocity variables. But we must also be       */
+            /* careful not to zero the velocities when we shouldn't*/
+            case SDL_KEYUP:
+                switch( event.key.keysym.sym ){
+                    case SDLK_LEFT:
+                        /* We check to make sure the alien is moving */
+                        /* to the left. If it is then we zero the    */
+                        /* velocity. If the alien is moving to the   */
+                        /* right then the right key is still press   */
+                        /* so we don't tocuh the velocity            */
+                        if( alien_xvel < 0 )
+                            alien_xvel = 0;
+                        break;
+                    case SDLK_RIGHT:
+                        if( alien_xvel > 0 )
+                            alien_xvel = 0;
+                        break;
+                    case SDLK_UP:
+                        if( alien_yvel < 0 )
+                            alien_yvel = 0;
+                        break;
+                    case SDLK_DOWN:
+                        if( alien_yvel > 0 )
+                            alien_yvel = 0;
+                        break;
+                    default:
+                        break;
+                }
+                break;
+            
+            default:
+                break;
+        }
+    }
+    .
+    .

    About SDL

    The SDL library is designed to make it easy to write games that run on Linux, *BSD, MacOS, Win32 and BeOS using the various native high-performance media interfaces, (for video, audio, etc) and presenting a single source-code level API to your application. SDL is a fairly low level API, but using it, completely portable applications can be written with a great deal of flexibility.

    Chapter 2. Graphics and Video

    Using OpenGL With SDL

    SDL has the ability to create and use OpenGL contexts on several platforms(Linux/X11, Win32, BeOS, MacOS Classic/Toolbox, MacOS X, FreeBSD/X11 and Solaris/X11). This allows you to use SDL's audio, event handling, threads and times in your OpenGL applications (a function often performed by GLUT).

    Initialisation

    Initialising SDL to use OpenGL is not very different to initialising SDL normally. There are three differences; you must pass SDL_OPENGL to SDL_SetVideoMode, you must specify several GL attributes (depth buffer size, framebuffer sizes) using SDL_GL_SetAttribute and finally, if you wish to use double buffering you must specify it as a GL attribute, not by passing the SDL_DOUBLEBUF flag to SDL_SetVideoMode. +

        /* Information about the current video settings. */
+    const SDL_VideoInfo* info = NULL;
+    /* Dimensions of our window. */
+    int width = 0;
+    int height = 0;
+    /* Color depth in bits of our window. */
+    int bpp = 0;
+    /* Flags we will pass into SDL_SetVideoMode. */
+    int flags = 0;
+
+    /* First, initialize SDL's video subsystem. */
+    if( SDL_Init( SDL_INIT_VIDEO ) < 0 ) {
+        /* Failed, exit. */
+        fprintf( stderr, "Video initialization failed: %s\n",
+             SDL_GetError( ) );
+        quit_tutorial( 1 );
+    }
+
+    /* Let's get some video information. */
+    info = SDL_GetVideoInfo( );
+
+    if( !info ) {
+        /* This should probably never happen. */
+        fprintf( stderr, "Video query failed: %s\n",
+             SDL_GetError( ) );
+        quit_tutorial( 1 );
+    }
+
+    /*
+     * Set our width/height to 640/480 (you would
+     * of course let the user decide this in a normal

+     * resolution, so this is probably being overly
+     * safe. Under Win32, ChangeDisplaySettings
+     * can change the bpp.
+     */
+    width = 640;
+    height = 480;
+    bpp = info->vfmt->BitsPerPixel;
+
+    /*

+    SDL_GL_SetAttribute( SDL_GL_DOUBLEBUFFER, 1 );

+     * with an OpenGL window, in a fullscreen
+     * video mode.
+     *
+     * EXERCISE:
+     * Make starting windowed an option, and

+     * glViewport.
+     */
+    flags = SDL_OPENGL | SDL_FULLSCREEN;
+
+    /*
+     * Set the video mode
+     */
+    if( SDL_SetVideoMode( width, height, bpp, flags ) == 0 ) {
+        /* 
+         * This could happen for a variety of reasons,
+         * including DISPLAY not being set, the specified
+         * resolution not being available, etc.
+         */
+        fprintf( stderr, "Video mode set failed: %s\n",
+             SDL_GetError( ) );
+        quit_tutorial( 1 );
+    }

    Drawing

    Apart from initialisation, using OpenGL within SDL is the same as using. However if you have request a double buffered display (using SDL_GL_SetAttribute) and one (which can be checked by using SDL_GL_GetAttribute), then you must use SDL_GL_SwapBuffers() to swap the buffers and update the display.

    A full example code listing is now presented below.

    Fastest possible surface blit

    There are three different ways you can draw an image to the screen: +

    1.Create a surface and use SDL_BlitSurface to blit it to the screen
    2.Create the video surface in system memory and call SDL_UpdateRect
    3.Create the video surface in video memory and call SDL_LockSurface

    +The best way to do this is to combine methods: +
    #include <stdio.h>
+#include <stdlib.h>
+#include "SDL.h"
+#include "SDL_timer.h"
+
+void ComplainAndExit(void)

    SDL_NumJoysticks — Count available joysticks.
    SDL_JoystickName — Get joystick name.
    SDL_JoystickOpen — Opens a joystick for use.
    SDL_JoystickOpened — Determine if a joystick has been opened

    Joysticks, and other similar input devices, have a very strong role in game playing and SDL provides comprehensive support for them. Axes, Buttons, POV Hats and trackballs are all supported.

    Joystick support is initialized by passed the SDL_INIT_JOYSTICK flag to SDL_Init. Once initilized joysticks must be opened using SDL_JoystickOpen.

    While using the functions describe in this secton may seem like the best way to access and read from joysticks, in most cases they aren't. Ideally joysticks should be read using the event system. To enable this, you must set the joystick event processing state with SDL_JoystickEventState. Joysticks must be opened before they can be used of course.

    Note: If you are not handling the joystick via the event queue then you must explicitly request a joystick update by calling SDL_JoystickUpdate.

    Note: Force Feedback is not yet support. Sam (slouken@libsdl.org) is soliciting suggestions from people with force-feedback experience on the best wat to desgin the API.

    SDL_ActiveEvent

    Name

    SDL_ActiveEvent -- Application visibility event structure

    Structure Definition

    typedef struct{
+  Uint8 type;
+  Uint8 gain;
+  Uint8 state;
+} SDL_ActiveEvent;

    Structure Data

    typeSDL_ACTIVEEVENT.
    gain0 if the event is a loss or 1 if it is a gain.
    stateSDL_APPMOUSEFOCUS if mouse focus was gained or lost, SDL_APPINPUTFOCUS if input focus was gained or lost, or SDL_APPACTIVE if the application was iconified (gain=0) or restored(gain=1).

    Description

    SDL_ActiveEvent is a member of the SDL_Event union and is used when an event of type SDL_ACTIVEEVENT is reported.

    When the mouse leaves or enters the window area a SDL_APPMOUSEFOCUS type activation event occurs, if the mouse entered the window then gain will be 1, otherwise gain will be 0. A SDL_APPINPUTFOCUS type activation event occurs when the application loses or gains keyboard focus. This usually occurs when another application is made active. Finally, a SDL_APPACTIVE type event occurs when the application is either minimised/iconified (gain=0) or restored.

    Note: This event does not occur when an application window is first created.

    SDL_AddTimer

    Name

    SDL_AddTimer -- Add a timer which will call a callback after the specified number of milliseconds has +elapsed.

    Synopsis

    #include "SDL.h"

    SDL_TimerID SDL_AddTimer(Uint32 interval, SDL_NewTimerCallback callback, void *param);

    Callback

    /* type definition for the "new" timer callback function */
+typedef Uint32 (*SDL_NewTimerCallback)(Uint32 interval, void *param);

    Description

    Adds a callback function to be run after the specified number of +milliseconds has elapsed. The callback function is passed the current +timer interval and the user supplied parameter from the +SDL_AddTimer call and returns the next timer +interval. If the returned value from the callback is the same as the one +passed in, the periodic alarm continues, otherwise a new alarm is +scheduled.

    To cancel a currently running timer call +SDL_RemoveTimer with the +timer ID returned from +SDL_AddTimer.

    The timer callback function may run in a different thread than your +main program, and so shouldn't call any functions from within itself.

    The maximum resolution of this timer is 10 ms, which means that if +you request a 16 ms timer, your callback will run approximately 20 ms +later on an unloaded system. If you wanted to set a flag signaling +a frame update at 30 frames per second (every 33 ms), you might set a +timer for 30 ms (see example below). + +If you use this function, you need to pass SDL_INIT_TIMER +to SDL_Init.

    Return Value

    Returns an ID value for the added timer or +NULL if there was an error.

    Examples

    my_timer_id = SDL_AddTimer((33/10)*10, my_callbackfunc, my_callback_param);

    len_ratioFinal audio size is len*len_ratio
    filters[10](..)Pointers to functions needed for this conversion
    filter_indexCurrent conversion function

    Description

    The SDL_AudioCVT is used to convert audio data between different formats. A SDL_AudioCVT structure is created with the SDL_BuildAudioCVT function, while the actual conversion is done by the SDL_ConvertAudio function.

    Many of the fields in the SDL_AudioCVT structure should be considered private and their function will not be discussed here.

    Uint8 *buf

    This points to the audio data that will be used in the conversion. It is both the source and the destination, which means the converted audio data overwrites the original data. It also means that the converted data may be larger than the original data (if you were converting from 8-bit to 16-bit, for instance), so you must ensure buf is large enough. See below.

    int len

    This is the length of the original audio data in bytes.

    int len_mult

    As explained above, the audio buffer needs to be big enough to store the converted data, which may be bigger than the original audio data. The length of buf should be len*len_mult.

    double len_ratio

    When you have finished converting your audio data, you need to know how much of your audio buffer is valid. len*len_ratio is the size of the converted audio data in bytes. This is very similar to len_mult, however when the convert audio data is shorter than the original len_mult would be 1. len_ratio, on the other hand, would be a fractional number between 0 and 1.

    Description

    The SDL_AudioSpec structure is used to describe the format of some audio data. This structure is used by SDL_OpenAudio and SDL_LoadWAV. While all fields are used by SDL_OpenAudio only freq, format, samples and channels are used by SDL_LoadWAV. We will detail these common members here.

    freq

    The number of samples sent to the sound device every second. Common values are 11025, 22050 and 44100. The higher the better.

    format

    Specifies the size and type of each sample element +

    AUDIO_U8

    Unsigned 8-bit samples

    AUDIO_S8

    Signed 8-bit samples

    AUDIO_U16 or AUDIO_U16LSB

    Unsigned 16-bit little-endian samples

    AUDIO_S16 or AUDIO_S16LSB

    Signed 16-bit little-endian samples

    AUDIO_U16MSB

    Unsigned 16-bit big-endian samples

    AUDIO_S16MSB

    Signed 16-bit big-endian samples

    AUDIO_U16SYS

    Either AUDIO_U16LSB or AUDIO_U16MSB depending on you systems endianness

    AUDIO_S16SYS

    Either AUDIO_S16LSB or AUDIO_S16MSB depending on you systems endianness

    channelsThe number of seperate sound channels. 1 is mono (single channel), 2 is stereo (dual channel).
    samplesWhen used with SDL_OpenAudio this refers to the size of the audio buffer in samples. A sample a chunk of audio data of the size specified in format mulitplied by the number of channels. When the SDL_AudioSpec is used with SDL_LoadWAV samples is set to 4096.

    SDL_BlitSurface

    Name

    SDL_BlitSurface -- This performs a fast blit from the source surface to the destination surface.

    Synopsis

    #include "SDL.h"

    int SDL_BlitSurface(SDL_Surface *src, SDL_Rect *srcrect, SDL_Surface *dst, SDL_Rect *dstrect);

    Description

    This performs a fast blit from the source surface to the destination surface.

    Only the position is used in the dstrect (the +width and height are ignored).

    If either srcrect or +dstrect are NULL, the entire +surface (src or dst) is +copied.

    The final blit rectangle is saved in +dstrect after all clipping is performed +(srcrect is not modified).

    The blit function should not be called on a locked surface.

    Note: The results of blitting operations vary greatly depending on whether SDL_SRCAPLHA is set or not. See SDL_SetAlpha.

    Return Value

    If the blit is successful, it returns 0, +otherwise it returns -1.

    If either of the surfaces were in video memory, and the blit returns +-2, the video memory was lost, so it should be +reloaded with artwork and re-blitted: +

            while ( SDL_BlitSurface(image, imgrect, screen, dstrect) == -2 ) {
+                while ( SDL_LockSurface(image)) < 0 )
+                        Sleep(10);
+                -- Write image pixels to image->pixels --
+                SDL_UnlockSurface(image);
+        }
    +This happens under DirectX 5.0 when the system switches away from your +fullscreen application. Locking the surface will also fail until you +have access to the video memory again.

    int SDL_BuildAudioCVT(SDL_AudioCVT *cvt, Uint16 src_format, Uint8 src_channels, int src_rate, Uint16 dst_format, Uint8 dst_channels, int dst_rate);

    Description

    Before an SDL_AudioCVT structure can be used to convert audio data it must be initialized with source and destination information.

    src_format and dst_format are the source and destination format of the conversion. (For information on audio formats see SDL_AudioSpec). src_channels and dst_channels are the number of channels in the source and destination formats. Finally, src_rate and dst_rate are the frequency or samples-per-second of the source and destination formats. Once again, see SDL_AudioSpec.

    Return Values

    Returns -1 if the filter could not be built or 1 if it could.

    Examples

    See SDL_ConvertAudio.

    SDL_ConvertAudio

    Name

    SDL_ConvertAudio -- Convert audio data to a desired audio format.

    Synopsis

    #include "SDL.h"

    int SDL_ConvertAudio(SDL_AudioCVT *cvt);

    Description

    SDL_ConvertAudio takes one parameter, cvt, which was previously initilized. Initilizing a SDL_AudioCVT is a two step process. First of all, the structure must be passed to SDL_BuildAudioCVT along with source and destination format parameters. Secondly, the cvt->buf and cvt->len fields must be setup. cvt->buf should point to the audio data and cvt->len should be set to the length of the audio data in bytes. Remember, the length of the buffer pointed to by buf show be len*len_mult bytes in length.

    Once the SDL_AudioCVTstructure is initilized then we can pass it to SDL_ConvertAudio, which will convert the audio data pointer to by cvt->buf. If SDL_ConvertAudio returned 0 then the conversion was completed successfully, otherwise -1 is returned.

    If the conversion completed successfully then the converted audio data can be read from cvt->buf. The amount of valid, converted, audio data in the buffer is equal to cvt->len*cvt->len_ratio.

    Examples

    Description

    Allocate an empty surface (must be called after SDL_SetVideoMode)

    If depth is 8 bits an empty palette is allocated for the surface, otherwise a 'packed-pixel' SDL_PixelFormat is created using the [RGBA]mask's provided (see SDL_PixelFormat). The flags specifies the type of surface that should be created, it is an OR'd combination of the following possible values.

    SDL_SWSURFACESDL will create the surface in system memory. This improves the performance of pixel level access, however you may not be able to take advantage of some types of hardware blitting.
    SDL_HWSURFACESDL will attempt to create the surface in video memory. This will allow SDL to take advantage of Video->Video blits (which are often accelerated).
    SDL_SRCCOLORKEYWith this flag SDL will attempt to find the best location for this surface, either in system memory or video memory, to obtain hardware colorkey blitting support.
    SDL_SRCALPHAWith this flag SDL will attempt to find the best location for this surface, either in system memory or video memory, to obtain hardware alpha support

    Description

    The SDL_Event union is the core to all event handling is SDL, its probably the most important structure after SDL_Surface. SDL_Event is a union of all event structures used in SDL, using it is a simple matter of knowing which union member relates to which event type.

    Event typeEvent Structure

    SDL_VIDEORESIZESDL_ResizeEvent
    SDL_USEREVENTSDL_UserEvent

    Use

    The SDL_Event structure has two uses

    • Reading events on the event queue

    • Placing events on the event queue

    Reading events from the event queue is done with either SDL_PollEvent or SDL_PeepEvents. We'll use SDL_PollEvent and step through an example.

    First off, we create an empty SDL_Event structure. +

    SDL_Event test_event;
    +SDL_PollEvent removes the next event from the event queue, if there are no events on the queue it returns 0 otherwise it returns 1. We use a while loop to process each event in turn. +
    while(SDL_PollEvent(&test_event)) {
    +The SDL_PollEvent function take a pointer to an SDL_Event structure that is to be filled with event information. We know that if SDL_PollEvent removes an event from the queue then the event information will be placed in our test_event structure, but we also know that the type of event will be placed in the type member of test_event. So to handle each event type seperately we use a switch statement. +
      switch(test_event.type) {
    +We need to know what kind of events we're looking for and the event type's of those events. So lets assume we want to detect where the user is moving the mouse pointer within our application. We look through our event types and notice that SDL_MOUSEMOTION is, more than likely, the event we're looking for. A little more research tells use that SDL_MOUSEMOTION events are handled within the SDL_MouseMotionEvent structure which is the motion member of SDL_Event. We can check for the SDL_MOUSEMOTION event type within our switch statement like so: +
        case SDL_MOUSEMOTION:
    +All we need do now is read the information out of the motion member of test_event. +
          printf("We got a motion event.\n");
+      printf("Current mouse position is: (%d, %d)\n", test_event.motion.x, test_event.motion.y);
+      break;
+    default:
+      printf("Unhandled Event!\n");
+      break;
+  }
+}
+printf("Event queue empty.\n");

    It is also possible to push events onto the event queue and so use it as a two-way communication path. Both SDL_PushEvent and SDL_PeepEvents allow you to place events onto the event queue. This is usually used to place a SDL_USEREVENT on the event queue, however you could use it to post fake input events if you wished. Creating your own events is a simple matter of choosing the event type you want, setting the type member and filling the appropriate member structure with information. +

    SDL_Event user_event;
+
+user_event.type=SDL_USEREVENT;
+user_event.user.code=2;
+user_event.user.data1=NULL;
+user_event.user.data2=NULL;
+SDL_PushEvent(&user_event);

    SDL_GetKeyState -- Get a snapshot of the current keyboard state

    Synopsis

    #include "SDL.h"

    Uint8 *SDL_GetKeyState(int *numkeys);

    Description

    Gets a snapshot of the current keyboard state. The current state is return as a pointer to an array, the size of this array is stored in numkeys. The array is indexed by the SDLK_* symbols. A value of 1 means the key is pressed and a value of 0 means its not.

    Note: Use SDL_PumpEvents to update the state array.

    Example

    Uint8 *keystate = SDL_GetKeyState(NULL);
+if ( keystate[SDLK_RETURN] ) printf("Return Key Pressed.\n");

The field which is the index of the joystick that reported the event and hat is the index of the hat (for a more detailed exlaination see the Joystick section). value is the current position of the hat. It is a logically OR'd combination of the following values (whose meanings should be pretty obvious:) :

    SDL_HAT_CENTERED
    SDL_HAT_UP
    SDL_HAT_RIGHT
    SDL_HAT_DOWN
    SDL_HAT_LEFT

    The following defines are also provided:

    SDL_HAT_RIGHTUP
    SDL_HAT_RIGHTDOWN
    SDL_HAT_LEFTUP
    SDL_HAT_LEFTDOWN

    int SDL_JoystickEventState(int state);

    Description

    This function is used to enable or disable joystick event processing. With joystick event processing disabled you will have to update joystick states with SDL_JoystickUpdate and read the joystick information manually. state is either SDL_QUERY, SDL_ENABLE or SDL_IGNORE.

    Note: Joystick event handling is prefered

    Return Value

    If state is SDL_QUERY then the current state is returned, otherwise the new processing state is returned.

    Name

    SDL_JoystickGetAxis -- Get the current state of an axis

    Synopsis

    #include "SDL.h"

    Sint16 SDL_JoystickGetAxis(SDL_Joystick *joystick, int axis);

    Description

    SDL_JoystickGetAxis returns the current state of the given axis on the given joystick.

    On most modern joysticks the X axis is usually represented by axis 0 and the Y axis by axis 1. The value returned by SDL_JoystickGetAxis is a signed integer (-32768 to 32768) representing the current position of the axis, it maybe necessary to impose certain tolerances on these values to account for jitter. It is worth noting that some joysticks use axes 2 and 3 for extra buttons.

    Return Value

    Returns a 16-bit signed integer representing the current position of the axis.

    Examples

    Sint16 x_move, y_move;
+SDL_Joystick *joy1;
+.
+.
+x_move=SDL_JoystickGetAxis(joy1, 0);
+y_move=SDL_JoystickGetAxis(joy1, 1);

    Description

    SDL_KeyboardEvent is a member of the SDL_Event union and is used when an event of type SDL_KEYDOWN or SDL_KEYUP is reported.

    The type and state actually report the same information, they just use different values to do it! A keyboard event occurs when a key is released (type=SDK_KEYUP or state=SDL_RELEASED) and when a key is pressed (type=SDL_KEYDOWN or state=SDL_PRESSED). The information on what key was pressed or released is in the keysym structure.

    Note: Repeating SDL_KEYDOWN events will occur if key repeat is enabled (see SDL_EnableKeyRepeat).

    Structure Data

    symSDL virtual keysym
    modCurrent key modifiers
    unicodeTranslated character

    Description

    The SDL_keysym structure is used by reporting key presses and releases since it is a part of the SDL_KeyboardEvent.

    The scancode field should generally be left alone, it is the hardware dependent scancode returned by the keyboard. The sym field is extremely useful. It is the SDL-defined value of the key (see SDL Key Syms. This field is very useful when you are checking for certain key presses, like so: +

    .
+.
+while(SDL_PollEvent(&event)){
+  switch(event.type){
+    case SDL_KEYDOWN:
+      if(event.key.keysym.sym==SDLK_LEFT)
+        move_left();
+      break;
+    .
+    .
+    .
+  }
+}
+.
+.
    +mod stores the current state of the keyboard modifiers as explained in SDL_GetModState. The unicode is only used when UNICODE translation is enabled with SDL_EnableUNICODE. If unicode is non-zero then this a the UNICODE character corresponding to the keypress. If the high 9 bits of the character are 0, then this maps to the equivalent ASCII character: +
    char ch;
+if ( (keysym.unicode & 0xFF80) == 0 ) {
+  ch = keysym.unicode & 0x7F;
+}
+else {
+  printf("An International Character.\n");
+}
    +UNICODE translation does have a slight overhead so don't enable it unless its needed.

    Synopsis

    #include "SDL.h"

    SDL_Rect **SDL_ListModes(SDL_PixelFormat *format, Uint32 flags);

    Description

    Return a pointer to an array of available screen dimensions for the given +format and video flags, sorted largest to smallest. Returns +NULL if there are no dimensions available for a particular +format, or -1 if any dimension is okay for +the given format.

    If format is NULL, the mode list +will be for the format returned by SDL_GetVideoInfo()->vfmt. The flag parameter is an OR'd combination of surface flags. The flags are the same as those used SDL_SetVideoMode and they play a strong role in deciding what modes are valid. For instance, if you pass SDL_HWSURFACE as a flag only modes that support hardware video surfaces will be returned.

    Example

    SDL_Rect **modes;
+int i;
+.
+.
+.
+
+/* Get available fullscreen/hardware modes */
+modes=SDL_ListModes(NULL, SDL_FULLSCREEN|SDL_HWSURFACE);

    Name

    SDL_LockSurface -- Lock a surface for directly access.

    Synopsis

    int SDL_LockSurface(SDL_Surface *surface);

    Description

    SDL_LockSurface sets up a surface for directly +accessing the pixels. Between calls to SDL_LockSurface +and SDL_UnlockSurface, you can write to and read from +surface->pixels, using the pixel format stored in +surface->format. Once you are done accessing the +surface, you should use SDL_UnlockSurface to release it.

    Not all surfaces require locking. +If SDL_MUSTLOCK(surface) +evaluates to 0, then you can read and write to the +surface at any time, and the pixel format of the surface will not change.

    No operating system or library calls should be made between lock/unlock +pairs, as critical system locks may be held during this time.

    It should be noted, that since SDL 1.1.8 surface locks are recursive. This means that you can lock a surface multiple times, but each lock must have a match unlock. +

        .
+    .
+    SDL_LockSurface( surface );
+    .
+    /* Surface is locked */
+    /* Direct pixel access on surface here */
+    .
+    SDL_LockSurface( surface );
+    .
+    /* More direct pixel access on surface */
+    .
+    SDL_UnlockSurface( surface );
+    /* Surface is still locked */
+    /* Note: Is versions < 1.1.8, the surface would have been */
+    /* no longer locked at this stage                         */
+    .
+    SDL_UnlockSurface( surface );
+    /* Surface is now unlocked */
+    .
+    .

    SDL_MouseButtonEvent is a member of the SDL_Event union and is used when an event of type SDL_MOUSEBUTTONDOWN or SDL_MOUSEBUTTONUP is reported.

    When a mouse button press or release is detected then number of the button pressed (from 1 to 255, with 1 usually being the left button and 2 the right) is placed into button, the position of the mouse when this event occured is stored in the x and the y fields. Like SDL_KeyboardEvent, information on whether the event was a press or a release event is stored in both the type and state fields, but this should be obvious.

    Description

    SDL_MouseMotionEvent is a member of the SDL_Event union and is used when an event of type SDL_MOUSEMOTION is reported.

    Simply put, a SDL_MOUSEMOTION type event occurs when a user moves the mouse within the application window or when SDL_WarpMouse is called. Both the absolute (x and y) and relative (xrel and yrel) coordinates are reported along with the current button states (state). The button state can be interpreted using the SDL_BUTTON macro (see SDL_GetMouseState).

    If the cursor is hidden (SDL_ShowCursor(0)) and the input is grabbed (SDL_WM_GrabInput(SDL_GRAB_ON)), then the mouse will give relative motion events even when the cursor reaches the edge fo the screen. This is currently only implemented on Windows and Linux/Unix-a-likes.

    Name

    SDL_OpenAudio -- Opens the audio device with the desired parameters.

    Synopsis

    #include "SDL.h"

    int SDL_OpenAudio(SDL_AudioSpec *desired, SDL_AudioSpec *obtained);

    Description

    This function opens the audio device with the desired parameters, and +returns 0 if successful, placing the actual hardware parameters in the +structure pointed to by obtained. If obtained is NULL, the audio +data passed to the callback function will be guaranteed to be in the +requested format, and will be automatically converted to the hardware +audio format if necessary. This function returns -1 if it failed +to open the audio device, or couldn't set up the audio thread.

    To open the audio device a desired SDL_AudioSpec must be created. +

    SDL_AudioSpec *desired;
+.
+.
+desired=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
    +You must then fill this structure with your desired audio specifications.

    desired->freq

    The desired audio frequency in samples-per-second.

    desired->format

    The desired audio format (see SDL_AudioSpec)

    desired->samples

    The desired size of the audio buffer in samples. This number should be a power of two, and may be adjusted by the audio driver to a value more suitable for the hardware. Good values seem to range between 512 and 8192 inclusive, depending on the application and CPU speed. Smaller values yield faster response time, but can lead to underflow if the application is doing heavy processing and cannot fill the audio buffer in time. A stereo sample consists of both right and left channels in LR ordering. Note that the number of samples is directly related to time by the following formula: ms = (samples*1000)/freq

    desired->callback

    This should be set to a function that will be called when the audio device is ready for more data. It is passed a pointer to the audio buffer, and the length in bytes of the audio buffer. This function usually runs in a separate thread, and so you should protect data structures that it accesses by calling SDL_LockAudio and SDL_UnlockAudio in your code. The callback prototype is: +

    void callback(void *userdata, Uint8 *stream, int len);
    +userdata is the pointer stored in userdata field of the SDL_AudioSpec. stream is a pointer to the audio buffer you want to fill with information and len is the length of the audio buffer in bytes.

    desired->userdata

    This pointer is passed as the first parameter to the callback function.

    SDL_OpenAudio reads these fields from the desired SDL_AudioSpec structure pass to the function and attempts to find an audio configuration matching your desired. As mentioned above, if the obtained parameter is NULL then SDL with convert from your desired audio settings to the hardware settings as it plays.

    If obtained is NULL then the desired SDL_AudioSpec is your working specification, otherwise the obtained SDL_AudioSpec becomes the working specification and the desirec specification can be deleted. The data in the working specification is used when building SDL_AudioCVT's for converting loaded data to the hardware format.

    SDL_OpenAudio calculates the size and silence fields for both the desired and obtained specifications. The size field stores the total size of the audio buffer in bytes, while the silence stores the value used to represent silence in the audio buffer

    The audio device starts out playing silence when it's opened, and should be enabled for playing by calling SDL_PauseAudio(0) when you are ready for your audio callback function to be called. Since the audio driver may modify the requested size of the audio buffer, you should allocate any local mixing buffers after you open the audio device.

    Examples

    /* Prototype of our callback function */
+void my_audio_callback(void *userdata, Uint8 *stream, int len);
+
+/* Open the audio device */
+SDL_AudioSpec *desired, *obtained;
+SDL_AudioSpec *hardware_spec;
+
+/* Allocate a desired SDL_AudioSpec */
+desired=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
+
+/* Allocate space for the obtained SDL_AudioSpec */
+obtained=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
+
+/* 22050Hz - FM Radio quality */
+desired->freq=22050;
+
+/* 16-bit signed audio */
+desired->format=AUDIO_S16LSB;
+
+/* Large audio buffer reduces risk of dropouts but increases response time */
+desired->samples=8192;
+
+/* Our callback function */
+desired->callback=my_audio_callback;
+
+desired->userdata=NULL;
+
+/* Open the audio device */
+if ( SDL_OpenAudio(desired, obtained) < 0 ){
+  fprintf(stderr, "Couldn't open audio: %s\n", SDL_GetError());
+  exit(-1);
+}
+/* desired spec is no longer needed */

    Name

    SDL_Palette -- Color palette for 8-bit pixel formats

    Structure Definition

    typedef struct{

+  SDL_Color *colors;
+} SDL_Palette;

    Structure Data

    ncolorsNumber of colors used in this palette
    colorsPointer to SDL_Color structures that make up the palette.

    Description

    Each pixel in an 8-bit surface is an index into the colors field of the SDL_Palette structure store in SDL_PixelFormat. A SDL_Palette should never need to be created manually. It is automatically created when SDL allocates a SDL_PixelFormat for a surface. The colors values of a SDL_Surfaces palette can be set with the SDL_SetColors.

    alphaOverall surface alpha value

    Description

    A SDL_PixelFormat describes the format of the pixel data stored at the pixels field of a SDL_Surface. Every surface stores a SDL_PixelFormat in the format field.

    If you wish to do pixel level modifications on a surface, then understanding how SDL stores its color information is essential.

    8-bit pixel formats are the easiest to understand. Since its an 8-bit format, we have 8 BitsPerPixel and 1 BytesPerPixel. Since BytesPerPixel is 1, all pixels are represented by a Uint8 which contains an index into palette->colors. So, to determine the color of a pixel in a 8-bit surface: we read the color index from surface->pixels and we use that index to read the SDL_Color structure from surface->format->palette->colors. Like so: +

    SDL_Surface *surface;
+SDL_PixelFormat *fmt;
+SDL_Color *color;
+Uint8 index;
+
+.
+.
+
+/* Create surface */
+.
+.
+fmt=surface->format;
+
+/* Check the bitdepth of the surface */
+if(fmt->BitsPerPixel!=8){
+  fprintf(stderr, "Not an 8-bit surface.\n");
+  return(-1);
+}
+
+/* Lock the surface */
+SDL_LockSurface(surface);
+
+/* Get the topleft pixel */
+index=*(Uint8 *)surface->pixels;
+color=fmt->palette->colors[index];
+
+/* Unlock the surface */
+SDL_UnlockSurface(surface);
+printf("Pixel Color-> Red: %d, Green: %d, Blue: %d. Index: %d\n",
+          color->r, color->g, color->b, index);
+.
+.

    Pixel formats above 8-bit are an entirely different experience. They are considered to be "TrueColor" formats and the color information is stored in the pixels themselves, not in a palette (packed-pixel). The mask, shift and loss fields tell us how the color information is encoded. The mask fields allow us to isolate each color component, the shift fields tell us how far left we have to shift the masked value and the loss fields tell us for far right we have to shift the final value to convert it to a full 8-bit color component. +

    /* Extracting color components from a 32-bit color value */

    void SDL_PumpEvents(void);

    Description

    Pumps the event loop, gathering events from the input devices.

    SDL_PumpEvents gathers all the pending input information from devices and places it on the event queue. Without calls to SDL_PumpEvents no events would ever be placed on the queue. Often calls the need for SDL_PumpEvents is hidden from the user since SDL_PollEvent and SDL_WaitEvent implicitly call SDL_PumpEvents. However, if you are not polling or waiting for events (e.g. your filtering them), then you must call SDL_PumpEvents to force an event queue update.

    Note: You can only call this function in the thread that set the video mode.

    SDL_QuitEvent is a member of the SDL_Event union and is used whan an event of type SDL_QUIT is reported.

    As can be seen, the SDL_QuitEvent structure serves no useful purpose. The event itself, on the other hand, is very important. If you filter out or ignore a quit event then it is impossible for the user to close the window. On the other hand, if you do accept a quit event then the application window will be closed, and screen updates will still report success event though the application will no longer be visible.

    Note: The macro SDL_QuitRequested will return non-zero if a quit event is pending

    SDL_SetAlpha

    Name

    SDL_SetAlpha -- Adjust the alpha properties of a surface

    Synopsis

    #include "SDL.h"

    int SDL_SetAlpha(SDL_Surface *surface, Uint32 flag, Uint8 alpha);

    Description

    Note: This function and the semantics of SDL alpha blending have changed since version 1.1.4. Up until version 1.1.5, an alpha value of 0 was considered opaque and a value of 255 was considered transparent. This has now been inverted: 0 (SDL_ALPHA_TRANSPARENT) is now considered transparent and 255 (SDL_ALPHA_OPAQUE) is now considered opaque.

    SDL_SetAlpha is used for setting the per-surface alpha and/or enabling and disabling per-pixel alpha blending.

    The surface parameter specifies which surface whose alpha attributes you wish to adjust. flags is used to specify whether alpha blending should be used (SDL_SRCALPHA) and whether the surface should use RLE acceleration for blitting (SDL_RLEACCEL). flags can be an OR'd combination of these two options, one of these options or 0. If SDL_SRCALPHA is not passed as a flag then all alpha information is ignored when blitting the surface. The alpha parameter is the per-surface alpha value, a surface need not have an alpha channel to use per-surface alpha and blitting can still be accelerated with SDL_RLEACCEL. Setting the per-surface alpha value to 0 disables per-surface alpha blending.

    Note: The per-surface alpha value of 128 is considered a special case and is optimised, so it's much faster than other per-surface values.

    Alpha effects surface blitting in the following ways:

    RGBA->RGB with SDL_SRCALPHA

    The source is alpha-blended with the destination, using the alpha channel. SDL_SRCCOLORKEY and the per-surface alpha are ignored.

    RGBA->RGB without SDL_SRCALPHA

    The RGB data is copied from the source. The source alpha channel and the per-surface alpha value are ignored.

    RGB->RGBA with SDL_SRCALPHA

    The source is alpha-blended with the destination using the per-surface alpha value. If SDL_SRCCOLORKEYliteral> is set, only the pixels not matching the colorkey value are copied.

    RGB->RGBA without SDL_SRCALPHA

    The RGB data is copied from the source and the destination alpha is zero to opaque. If SDL_SRCCOLORKEY is set, only the pixels not matching the colorkey value are copied.

    RGBA->RGBA with SDL_SRCALPHA

    The source is alpha-blended with the destination using the source alpha channel. The alpha channel in the destination surface is left untouched. SDL_SRCCOLORKEY is ignored.

    RGBA->RGBA without SDL_SRCALPHA

    The RGBA data is copied to the destination surface. If SDL_SRCCOLORKEY is set, only the pixels not matching the colorkey value are copied.

    RGB->RGB with SDL_SRCALPHA

    The source is alpha-blended with the destination using the per-surface alpha value. If SDL_SRCCOLORKEY is set, only the pixels not matching the colorkey value are copied.

    RGB->RGB without SDL_SRCALPHA

    The RGB data is copied from the source. If SDL_SRCCOLORKEY is set, only the pixels not matching the colorkey value are copied.

    Synopsis

    int SDL_SetColorKey(SDL_Surface *surface, Uint32 flag, Uint32 key);

    Description

    Sets the color key (transparent pixel) in a blittable surface and enables or + disables RLE blit acceleration.

    RLE acceleration can substantially speed up blitting of images with large +horizontal runs of transparent pixels (i.e., pixels that match the +key value). The key must be of the same pixel format as the surface, SDL_MapRGB is often useful for obtaining an acceptable value.

    If flag is SDL_SRCCOLORKEY then +key is the transparent pixel value in the source image of a +blit.

    If flag is OR'd with +SDL_RLEACCEL then the surface will be draw using RLE +acceleration when drawn with +SDL_BlitSurface. The surface will +actually be encoded for RLE acceleration the first time +SDL_BlitSurface or +SDL_DisplayFormat is called on the +surface.

    If flag is 0, this function clears +any current color key.

    Return Value

    This function returns 0, or +-1 if there was an error.

    Synopsis

    #include "SDL.h"

    int SDL_SetColors(SDL_Surface *surface, SDL_Color *colors, int firstcolor, int ncolors);

    Description

    Sets a portion of the colormap for the given 8-bit surface.

    When surface is the surface associated with the current +display, the display colormap will be updated with the requested colors. If +SDL_HWPALETTE was set in SDL_SetVideoMode flags, +SDL_SetColors will always return 1, +and the palette is guaranteed to be set the way you desire, even if the window +colormap has to be warped or run under emulation.

    The color components of a +SDL_Color +structure are 8-bits in size, giving you a total of 2563 +=16777216 colors.

    Palettized (8-bit) screen surfaces with the SDL_HWPALETTE +flag have two palettes, a logical palette that is used for mapping blits +to/from the surface and a physical palette (that determines how the +hardware will map the colors to the display). SDL_SetColors +modifies both palettes (if present), and is equivalent to calling +SDL_SetPalette with the +flags set to +(SDL_LOGPAL | SDL_PHYSPAL).

    Return Value

    If surface is not a palettized surface, this function +does nothing, returning 0. If all of the colors were set +as passed to SDL_SetColors, it will return +1. If not all the color entries were set exactly as +given, it will return 0, and you should look at the +surface palette to determine the actual color palette.

    void SDL_SetEventFilter(SDL_EventFilter filter);

    Description

    This function sets up a filter to process all events before they are posted +to the event queue. This is a very powerful and flexible feature. The filter +is prototyped as: +

    typedef int (*SDL_EventFilter)(const SDL_Event *event);
    +If the filter returns 1, then the event will be +added to the internal queue. If it returns 0, +then the event will be dropped from the queue. This allows selective +filtering of dynamically.

    There is one caveat when dealing with the SDL_QUITEVENT event type. The +event filter is only called when the window manager desires to close the +application window. If the event filter returns 1, then the window will +be closed, otherwise the window will remain open if possible. +If the quit event is generated by an interrupt signal, it will bypass the +internal queue and be delivered to the application at the next event poll.

    Note: Events pushed onto the queue with SDL_PushEvent or SDL_PeepEvents do not get passed through the event filter.

    Note: Be Careful! The event filter function may run in a different thread so be careful what you do within it.

    Description

    Sets a portion of the palette for the given 8-bit surface.

    Palettized (8-bit) screen surfaces with the +SDL_HWPALETTE flag have two palettes, a logical +palette that is used for mapping blits to/from the surface and a +physical palette (that determines how the hardware will map the colors +to the display). SDL_BlitSurface +always uses the logical palette when blitting surfaces (if it has to +convert between surface pixel formats). Because of this, it is often +useful to modify only one or the other palette to achieve various +special color effects (e.g., screen fading, color flashes, screen dimming).

    This function can modify either the logical or physical palette by +specifing SDL_LOGPAL or +SDL_PHYSPALthe in the flags +parameter.

    When surface is the surface associated with the current +display, the display colormap will be updated with the requested colors. If +SDL_HWPALETTE was set in SDL_SetVideoMode flags, +SDL_SetPalette will always return 1, +and the palette is guaranteed to be set the way you desire, even if the window +colormap has to be warped or run under emulation.

    The color components of a +SDL_Color structure +are 8-bits in size, giving you a total of +2563=16777216 colors.

    Return Value

    If surface is not a palettized surface, this function +does nothing, returning 0. If all of the colors were set +as passed to SDL_SetPalette, it will return +1. If not all the color entries were set exactly as +given, it will return 0, and you should look at the +surface palette to determine the actual color palette.

    Callback

    /* Function prototype for the timer callback function */ +typedef Uint32 (*SDL_TimerCallback)(Uint32 interval);

    Description

    Set a callback to run after the specified number of milliseconds has +elapsed. The callback function is passed the current timer interval +and returns the next timer interval. If the returned value is the +same as the one passed in, the periodic alarm continues, otherwise a +new alarm is scheduled.

    To cancel a currently running timer, call +SDL_SetTimer(0, NULL);

    The timer callback function may run in a different thread than your +main constant, and so shouldn't call any functions from within itself.

    The maximum resolution of this timer is 10 ms, which means that if +you request a 16 ms timer, your callback will run approximately 20 ms +later on an unloaded system. If you wanted to set a flag signaling +a frame update at 30 frames per second (every 33 ms), you might set a +timer for 30 ms (see example below).

    If you use this function, you need to pass SDL_INIT_TIMER +to SDL_Init().

    Note: This function is kept for compatibility but has been superceeded +by the new timer functions +SDL_AddTimer and +SDL_RemoveTimer which support +multiple timers.

    Examples

    SDL_SetTimer((33/10)*10, my_callback);

    The flags parameter is the same as the flags field of the SDL_Surface structure. OR'd combinations of the following values are valid.

    SDL_SWSURFACECreate the video surface in system memory
    SDL_HWSURFACECreate the video surface in video memory
    SDL_ASYNCBLITEnables the use of asynchronous to the display surface. This will usually slow down blitting on single CPU machines, but may provide a speed increase on SMP systems.
    SDL_ANYFORMATNormally, if a video surface of the requested depth (bpp) is not available, SDL will emulate one with a shadow surface. Passing SDL_ANYFORMAT prevents this and causes SDL to use the video surface, regardless of its depth.
    SDL_HWPALETTEGive SDL exclusive palette access. Without this flag you may not always get the the colors you request with SDL_SetColors.
    SDL_DOUBLEBUFEnable double buffering. Calling SDL_Flip will flip the buffers and update the screen. If double buffering could not be enabled then SDL_Flip will just perform a SDL_UpdateRect on the entire screen.
    SDL_FULLSCREENSDL will attempt to use a fullscreen mode
    SDL_OPENGLCreate an OpenGL rendering context. You should have previously set OpenGL video attributes with SDL_GL_SetAttribute.
    SDL_OPENGLBLITCreate an OpenGL rendering context, like above, but allow normal blitting operations.
    SDL_RESIZABLECreate a resizable window. When the window is resized by the user a SDL_VIDEORESIZE event is generated and SDL_SetVideoMode can be called again with the new size.
    SDL_NOFRAMEIf possible, SDL_NOFRAME causes SDL to create a window with no title bar or frame decoration. Fullscreen modes automatically have this flag set.

    pitchLength of a surface scanline in bytes
    pixelsPointer to the actual pixel data
    clip_minx, clip_maxxX clip coords
    clip_rectsurface clip rectangle

    Description

    SDL_Surface's represent areas of "graphical" +memory, memory that can be drawn to. The video framebuffer is returned +as a SDL_Surface by +SDL_SetVideoMode +and SDL_GetVideoSurface. +Most of the fields should be pretty obvious. +w and h are the +width and height of the surface in pixels. +pixels is a pointer to the actual pixel data, +the surface should be locked +before accessing this field. The clip_rect field +is the clipping rectangle as set by +SDL_SetClipRect.

    The following are supported in the +flags field.

    SDL_SWSURFACESurface is stored in system memory
    SDL_HWSURFACESurface is stored in video memory
    SDL_ASYNCBLITSurface uses asynchronous blits if possible
    SDL_ANYFORMATAllows any pixel-format (Display surface)
    SDL_HWPALETTESurface has exclusive palette
    SDL_DOUBLEBUFSurface is double buffered (Display surface)
    SDL_FULLSCREENSurface is full screen (Display Surface)
    SDL_OPENGLSurface has an OpenGL context (Display Surface)
    SDL_OPENGLBLITSurface supports OpenGL blitting (Display Surface)
    SDL_RESIZABLESurface is resizable (Display Surface)
    SDL_HWACCELSurface blit uses hardware acceleration
    SDL_SRCOLORKEYSurface use colorkey blitting
    SDL_RLEACCELColorkey blitting is accelerated with RLE
    SDL_SRCALPHASurface blit uses alpha blending
    SDL_PREALLOCSurface uses preallocated memory

    Name

    SDL_SysWMEvent -- Platform-dependent window manager event.

    Description

    The system window manager event contains a pointer to system-specific +information about unknown window manager events. If you enable this event +using +SDL_EventState(), +it will be generated whenever unhandled events are received from the window +manager. This can be used, for example, to implement cut-and-paste in your +application. + +

+ } SDL_SysWMEvent;
    + +If you want to obtain system-specific information about the window manager, +you can fill the version member of a SDL_SysWMinfo +structure (details can be found in SDL_syswm.h, which must be included) using the SDL_VERSION() macro found in +SDL_version.h, and pass it to the +function: +

    SDL provides functions for creating threads, mutexes, semphores and condition variables.

    In general, you must be very aware of concurrency and data integrity issues +when writing multi-threaded programs. Some good guidelines include: +

    • Don't call SDL video/event functions from separate threads

    • Don't use any library functions in separate threads

    • Don't perform any memory management in separate threads

    • Lock global variables which may be accessed by multiple threads

    • Never terminate threads, always set a flag and wait for them to quit

    • Think very carefully about all possible ways your code may interact

    Note: SDL's threading is not implemented on MacOS, due to that lack of preemptive thread support (eck!)

    SDL provides several cross-platform functions for dealing with time. +It provides a way to get the current time, a way to wait a little while, +and a simple timer mechanism. These functions give you two ways of moving an +object every x milliseconds: + +

    • Use a timer callback function. This may have the bad effect that it runs in a seperate thread or uses alarm signals, but it's easier to implement.

    • Or you can get the number of milliseconds passed, and move the object if, for example, 30 ms passed.

    SDL presents a very simple interface to the display framebuffer. The +framebuffer is represented as an offscreen surface to which you can write +directly. If you want the screen to show what you have written, call the update function which will +guarantee that the desired portion of the screen is updated.

    Before you call any of the SDL video functions, you must first call +SDL_Init(SDL_INIT_VIDEO), which initializes the video +and events in the SDL library. Check the return code, which should be +0, to see if there were any errors in starting up.

    If you use both sound and video in your application, you need to call +SDL_Init(SDL_INIT_AUDIO | SDL_INIT_VIDEO) before opening the +sound device, otherwise under Win32 DirectX, you won't be able to set +full-screen display modes.

    After you have initialized the library, you can start up the video display in a +number of ways. The easiest way is to pick a common screen resolution and +depth and just initialize the video, checking for errors. You will probably +get what you want, but SDL may be emulating your requested mode and converting +the display on update. The best way is to +query, for the best +video mode closest to the desired one, and then +convert +your images to that pixel format.

    SDL currently supports any bit depth >= 8 bits per pixel. 8 bpp formats are +considered 8-bit palettized modes, while 12, 15, 16, 24, and 32 bits per pixel +are considered "packed pixel" modes, meaning each pixel contains the RGB color +components packed in the bits of the pixel.

    After you have initialized your video mode, you can take the surface that was +returned, and write to it like any other framebuffer, calling the update +routine as you go.

    When you have finished your video access and are ready to quit your +application, you should call "SDL_Quit()" to shutdown the +video and events.

    Introduction

    This library is designed to make it easy to write games that run on Linux, +Win32 and BeOS using the various native high-performance media interfaces, +(for video, audio, etc) and presenting a single source-code level API to +your application. This is a fairly low level API, but using this, completely +portable applications can be written with a great deal of flexibility.

    The library is loaded as a dynamically linked library on its native +platform, and is currently compiled natively for Linux, compiled for +Win32 using a Linux hosted GCC +cross-compilation +environment, and compiled using the EGCS C++ compiler under BeOS.

    An introduction to SDL can be found online at: +http://www.libsdl.org/intro/

    There are code examples on each of the main library pages, and there are +fully fleshed example C++ classes and programs in the examples archive, +available on the +SDL download page.

    For an introduction to basic multi-media programming concepts, you might try +some of the following links: +

    Enjoy!
