sdlVulkanGetInstanceExtensions function

Pointer<Pointer<Int8>> sdlVulkanGetInstanceExtensions(Pointer<Uint32> count)

Get the Vulkan instance extensions needed for vkCreateInstance.

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.

\param count a pointer filled in with the number of extensions returned. \returns an array of extension name strings on success, NULL on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
