NAME

SDL_Vulkan_GetInstanceExtensions - Get the Vulkan instance extensions needed for vkCreateInstance.

HEADER FILE

Defined in SDL3/SDL_vulkan.h

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

(char const const ) Returns an array of extension name strings on success, NULL on failure; call SDL_GetError () for more information.

AVAILABILITY

This function is available since SDL 3.2.0.
