*
|

* The master copy of khrplatform.h is maintained in the Khronos EGL

* Registry repository at https://github.com/KhronosGroup/EGL-Registry
|

* The last semantic modification to khrplatform.h was at commit ID:

|

* 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 filing pull requests or issues on
|
||||
* the EGL Registry repository linked above.
|
||||
*
|
||||
*
|
||||
* 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
