/* Khronos platform-specific types and definitions. | |||||
* | |||||
* 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: | |||||
* 67a3e0864c2d75ea5287b9f3d2eb74a745936692 | |||||
* | |||||
* 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 | |||||
* KHRONOS_APIATTRIBUTES | |||||
* | |||||
* These may be used in function prototypes as: | |||||
