                       int index, Uint32 flags);

Function Parameters

window 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
flags 0, or one or more SDL_RendererFlags OR'd together

Return Value

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


This function is available since SDL 2.0.0.
