30 * Adopters may modify this file to suit their platform. Adopters are
31 * encouraged to submit platform specific modifications to the Khronos
32 * group so that they can be included in future versions of this file.
33 * Please submit changes by sending them to the public Khronos Bugzilla
34 * (http://khronos.org/bugzilla) by filing a bug against product
35 * "Khronos (general)" component "Registry".
37 * A predefined template which fills in some of the bug fields can be
38 * reached using http://tinyurl.com/khrplatform-h-bugreport, but you
39 * must create a Bugzilla login first.
42 * See the Implementer's Guidelines for information about where this file
43 * should be located on your system.
44 * http://www.khronos.org/registry/implementers_guide.pdf
47 * This file should be included as
48 * #include <KHR/khrplatform.h>
49 * by the Khronos API header file that uses its types and defines.
51 * The types in this file should only be used to define API-specific types.
52 * Types defined in this file:
53 * khronos_int8_t signed 8 bit
54 * khronos_uint8_t unsigned 8 bit
55 * khronos_int16_t signed 16 bit
56 * khronos_uint16_t unsigned 16 bit
57 * khronos_int32_t signed 32 bit
58 * khronos_uint32_t unsigned 32 bit
59 * khronos_int64_t signed 64 bit
60 * khronos_uint64_t unsigned 64 bit
61 * khronos_intptr_t signed same number of bits as a pointer
62 * khronos_uintptr_t unsigned same number of bits as a pointer
63 * khronos_ssize_t signed size
64 * khronos_usize_t unsigned size
65 * khronos_float_t signed 32 bit floating point
66 * khronos_time_ns_t unsigned 64 bit time in nanoseconds
67 * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
69 * khronos_stime_nanoseconds_t signed time interval in nanoseconds
71 * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
72 * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
75 * Macros defined in this file:
78 * KHRONOS_APIATTRIBUTES
79 * These may be used in function prototypes as:
80 * KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
82 * int arg2) KHRONOS_APIATTRIBUTES;
