NAME
SDL_CreateSoftwareRenderer - Create a 2D software rendering context for a surface.
SYNOPSIS
#include <SDL3/SDL_render.h>
SDL_Renderer * SDL_CreateSoftwareRenderer(SDL_Surface *surface);
DESCRIPTION
Two other API 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.
FUNCTION PARAMETERS
surface
the SDL_Surface structure representing the surface where rendering is done.
RETURN VALUE
Returns a valid rendering context or NULL if there was an error; call SDL_GetError() for more
information.
THREAD SAFETY
This function should only be called on the main thread.
AVAILABILITY
This function is available since SDL 3.2.0.
