/* Platform-specific calling convention macros.
|
|
*
|
|
* Platforms should define these so that OpenXR clients call OpenXR functions
|
|
* with the same calling conventions that the OpenXR implementation expects.
|
|
*
|
|
* XRAPI_ATTR - Placed before the return type in function declarations.
|
|
* Useful for C++11 and GCC/Clang-style function attribute syntax.
|
|
* XRAPI_CALL - Placed after the return type in function declarations.
|
|
* Useful for MSVC-style calling convention syntax.
|
|
* XRAPI_PTR - Placed between the '(' and '*' in function pointer types.
|
|
*
|
|
* Function declaration: XRAPI_ATTR void XRAPI_CALL xrFunction(void);
|
|
* Function pointer type: typedef void (XRAPI_PTR *PFN_xrFunction)(void);
