| /* 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); | |

| // calling convention, i.e. float parameters are passed in registers. This | |
| // is true even if the rest of the application passes floats on the stack, | |
| // as it does by default when compiling for the armeabi-v7a NDK ABI. | |
| // On other platforms, use the default calling convention | |
