# VK_NO_PROTOTYPES(3) Manual Page

## Name

VK_NO_PROTOTYPES - Vulkan header file prototype inclusion control

Loading… please wait.

## Description

If the `VK_NO_PROTOTYPES` macro is defined by an application at compile time, prototypes for Vulkan APIs will not be included. Only typedefs for API function pointers will be defined.

This is intended for applications using their own function loader and dispatch mechanism.

If the macro is not defined by the application, prototypes for Vulkan APIs will be included.
