/* 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);
