/* Platform-specific calling convention macros.
 *
 * Platforms should define these so that Vulkan clients call Vulkan commands
 * with the same calling conventions that the Vulkan implementation expects.
 *
 * 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);
