SDL_CreateSoftwareRenderer - Man Page

#include <SDL3/SDL_render.h>

SDL_Renderer * SDL_CreateSoftwareRenderer(SDL_Surface *surface);

Two other APIs which can be used to create SDL_Renderer: SDL_CreateRenderer() and SDL_CreateWindowAndRenderer(). These can _also_ create a software renderer, but they are intended to be used with an SDL_Window as the final destination and not an SDL_Surface.

surface

the SDL_Surface structure representing the surface where rendering is done.

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

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
