* Adopters may modify this file to suit their platform. Adopters are

* encouraged to submit platform specific modifications to the Khronos

* group so that they can be included in future versions of this file.

* Please submit changes by sending them to the public Khronos Bugzilla

* (http://khronos.org/bugzilla) by filing a bug against product

* "Khronos (general)" component "Registry".

*

* A predefined template which fills in some of the bug fields can be

* reached using http://tinyurl.com/khrplatform-h-bugreport, but you

* must create a Bugzilla login first.

*

*

* See the Implementer's Guidelines for information about where this file

* should be located on your system and for more details of its use:

* http://www.khronos.org/registry/implementers_guide.pdf

*

* This file should be included as

* #include <KHR/khrplatform.h>

* by Khronos client API header files that use its types and defines.

*

* The types in khrplatform.h should only be used to define API-specific types.

*

* Types defined in khrplatform.h:

* khronos_int8_t signed 8 bit

* khronos_uint8_t unsigned 8 bit

* khronos_int16_t signed 16 bit

* khronos_uint16_t unsigned 16 bit

* khronos_int32_t signed 32 bit

* khronos_uint32_t unsigned 32 bit

* khronos_int64_t signed 64 bit

* khronos_uint64_t unsigned 64 bit

* khronos_intptr_t signed same number of bits as a pointer

* khronos_uintptr_t unsigned same number of bits as a pointer

* khronos_ssize_t signed size

* khronos_usize_t unsigned size

* khronos_float_t signed 32 bit floating point

* khronos_time_ns_t unsigned 64 bit time in nanoseconds

* khronos_utime_nanoseconds_t unsigned time interval or absolute time in

* nanoseconds

* khronos_stime_nanoseconds_t signed time interval in nanoseconds

* khronos_boolean_enum_t enumerated boolean type. This should

* only be used as a base type when a client API's boolean type is

* an enum. Client APIs which use an integer or other type for

* booleans cannot use this as the base type for their boolean.

*

* Tokens defined in khrplatform.h:

*

* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.

*

* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.

* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.

*

* Calling convention macros defined in this file:

* KHRONOS_APICALL

* KHRONOS_APIENTRY

* KHRONOS_APIATTRIBUTES

*

* These may be used in function prototypes as:

*

* KHRONOS_APICALL void KHRONOS_APIENTRY funcname(

* int arg1,

* int arg2) KHRONOS_APIATTRIBUTES;
