| * VKAPI_ATTR - Placed before the return type in function declarations. | ||||
| * Useful for C++11 and GCC/Clang-style function attribute syntax. | ||||
| * VKAPI_CALL - Placed after the return type in function declarations. | ||||
| * Useful for MSVC-style calling convention syntax. | ||||
| * VKAPI_PTR - Placed between the '(' and '*' in function pointer types. | ||||
| * | ||||
| * Function declaration: VKAPI_ATTR void VKAPI_CALL vkCommand(void); | ||||
| * Function pointer type: typedef void (VKAPI_PTR *PFN_vkCommand)(void); | ||||
