* 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

* 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,
