====== (This is the documentation for SDL3, which is under heavy development and the API is changing! [https://wiki.libsdl.org/SDL2/ SDL2] is the current stable version!) ======
= SDL_CreateWindowAndRenderer =
Create a window and default renderer.
== Syntax ==
int SDL_CreateWindowAndRenderer(int width, int height, Uint32 window_flags, SDL_Window **window, SDL_Renderer **renderer);
== Function Parameters ==
{|
|'''width'''
|the width of the window
|-
|'''height'''
|the height of the window
|-
|'''window_flags'''
|the flags used to create the window (see [[SDL_CreateWindow]]())
|-
|'''window'''
|a pointer filled with the window, or NULL on error
|-
|'''renderer'''
|a pointer filled with the renderer, or NULL on error
|}
== Return Value ==
Returns 0 on success, or -1 on error; call [[SDL_GetError]]() for more
information.
== Version ==
This function is available since SDL 3.0.0.
== Code Examples ==
