* 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.
|

|
|
* KHRONOS_APIATTRIBUTES
|

|
*
|

|
|
* These may be used in function prototypes as:
