/* Platform-specific calling convention macros.

26
 *

27
 * Platforms should define these so that Vulkan clients call Vulkan commands

28
 * with the same calling conventions that the Vulkan implementation expects.

29
 *

30
 * VKAPI_ATTR - Placed before the return type in function declarations.

31
 *              Useful for C++11 and GCC/Clang-style function attribute syntax.

32
 * VKAPI_CALL - Placed after the return type in function declarations.

33
 *              Useful for MSVC-style calling convention syntax.

34
 * VKAPI_PTR  - Placed between the '(' and '*' in function pointer types.

35
 *

36
 * Function declaration:  VKAPI_ATTR void VKAPI_CALL vkCommand(void);

37
 * Function pointer type: typedef void (VKAPI_PTR *PFN_vkCommand)(void);
