NAME¶

SDL_CreateRenderer - Create a 2D rendering context for a window.

HEADER FILE¶

Defined in SDL3/SDL_render.h

SYNOPSIS¶

#include "SDL3/SDL.h"

SDL_Renderer * SDL_CreateRenderer(SDL_Window *window, const char *name);

DESCRIPTION¶

If you want a specific renderer, you can specify its name here. A list of available renderers can be obtained by calling

SDL_GetRenderDriver () multiple times, with indices from 0 to SDL_GetNumRenderDrivers ()-1. If you don't need a specific renderer, specify NULL and SDL will attempt to choose the best option for you, based on what is available on the user's system.

By default the rendering size matches the window size in pixels, but you can call

SDL_SetRenderLogicalPresentation () to change the content size and scaling options.

FUNCTION PARAMETERS¶

window

the window where rendering is displayed.

name

the name of the rendering driver to initialize, or NULL to let SDL choose one.

RETURN VALUE¶

( SDL_Renderer
*) Returns a valid rendering context or NULL if there was an error; call SDL_GetError () for more information.

THREAD SAFETY¶

You may only call this function from the main thread.

AVAILABILITY¶

This function is available since SDL 3.1.3.
