SDL_CreateRenderer - Man Page

Defined in SDL3/SDL_render.h

#include "SDL3/SDL.h"

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

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.

If name is a comma-separated list, SDL will try each name, in the order listed, until one succeeds or all of them fail.

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.

window

the window where rendering is displayed.

name

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

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

This function should only be called on the main thread.

This function is available since SDL 3.2.0.
