35/* Platform-specific calling convention macros.
36 *
37 * Platforms should define these so that Vulkan clients call Vulkan commands
38 * with the same calling conventions that the Vulkan implementation expects.
39 *
40 * VKAPI_ATTR - Placed before the return type in function declarations.
41 *              Useful for C++11 and GCC/Clang-style function attribute syntax.
42 * VKAPI_CALL - Placed after the return type in function declarations.
43 *              Useful for MSVC-style calling convention syntax.
44 * VKAPI_PTR  - Placed between the '(' and '*' in function pointer types.
45 *
46 * Function declaration:  VKAPI_ATTR void VKAPI_CALL vkCommand(void);
47 * Function pointer type: typedef void (VKAPI_PTR *PFN_vkCommand)(void);
