int index,
Uint32 flags)
Function Parameters
windowID |
the 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 |

Code Examples
You can add your code example here
Remarks
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.
