NAME¶

SDL_Vulkan_GetInstanceExtensions - Get the Vulkan instance extensions needed for vkCreateInstance.

SYNOPSIS¶

#include "SDL3/SDL.h"

char const* const* SDL_Vulkan_GetInstanceExtensions(Uint32 *count);

DESCRIPTION¶

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¶

Returns An array of extension name strings on success, NULL on error.

AVAILABILITY¶

This function is available since SDL 3.0.0.
