* 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

// effort of creating and loading with the large numbers of built-in
|

// symbols.
|

//
|

// * Name mangling will be used to give each function a unique name
|

// so that symbol table lookups are never ambiguous. This allows
|
||||
// a simpler symbol table structure.
|
||||
//
|
||||
// * Pushing and popping of scope, so symbol table will really be a stack
|
||||
// of symbol tables. Searched from the top, with new inserts going into
|
||||
// the top.
|
||||
//
|
||||
// * Constants: Compile time constant symbols will keep their values
|
||||
// in the symbol table. The parser can substitute constants at parse
|
||||
// time, including doing constant folding and constant propagation.
|

//
|
