Syntax

int SDL_CreateRenderer(SDL_Window* window,
                       int         index,
                       Uint32      flags)

window	the SDL_Window where rendering is displayed
index	the index of the rendering driver to initialize, or -1 to initialize the first one supporting the requested flags
flags	0, or one or more SDL_RendererFlags OR'd together; see Remarks for details

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

You can add your code example here

flags can have any number of these values OR'd in:

SDL_RENDERER_SOFTWARE	the renderer is a software fallback
SDL_RENDERER_ACCELERATED	the renderer uses hardware acceleration
SDL_RENDERER_PRESENTVSYNC	present is synchronized with the refresh rate
SDL_RENDERER_TARGETTEXTURE	the renderer supports rendering to texture

Note that providing no flags gives priority to available SDL_RENDERER_ACCELERATED renderers.
