/* SDL stdinc inline functions:
icculus@7003
   241
icculus@7003
   242
   The theory here is that, by default, we forcibly inline what we can--with
icculus@7003
   243
   real inline functions that avoid macro side-effects--and your app will use
icculus@7003
   244
   the inline version by default. However, we expose a non-inline version
icculus@7003
   245
   too, which internally just wraps the inline version in a real function,
icculus@7003
   246
   so the symbol is always available in the library even if your app
icculus@7003
   247
   bypassed it with the inline version. The SDL_*_inline versions aren't
icculus@7003
   248
   guaranteed to exist, so never call them directly; use SDL_* instead,
icculus@7003
   249
   and trust the system to give you the right thing.
icculus@7003
   250
icculus@7003
   251
   The benefit here is that you can dlsym() these functions, which you
icculus@7003
   252
   couldn't if you had macros, you can link against a foreign build of SDL
icculus@7003
   253
   even if you configured differently, and you can drop the unconfigured SDL
icculus@7003
   254
   headers into a project without #defining HAVE_MALLOC (etc) and still link.
