* 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; |
