SDL_Vulkan_GetInstanceExtensions3
Get the vulkan instance extensions needed for vkcreateinstance.
Usage
#include "SDL3/SDL.h"
char const * const * SDL_Vulkan_GetInstanceExtensions(Uint32 *count);
Header file
Defined in SDL3/SDL_vulkan.h
Overview
This should be called after either calling
SDL_Vulkan_LoadLibrary () or creating an
SDL_Window
with the SDL_WINDOW_VULKAN flag.
On return, the variable pointed to by count will be set to the number of elements returned, suitable for using with VkInstanceCreateInfo::enabledExtensionCount, and the returned array can be used with VkInstanceCreateInfo::ppEnabledExtensionNames, for calling Vulkan's vkCreateInstance API.
You should not free the returned array; it is owned by SDL.
Function parameters
- count
-
a pointer filled in with the number of extensions returned.
Return value
(char const const ) Returns an array of extension name strings on success, NULL on failure; call SDL_GetError () for more information.
