sdlGlGetSwapInterval function

int sdlGlGetSwapInterval()

Get the swap interval for the current OpenGL context.

If the system can't determine the swap interval, or there isn't a valid current context, this function will return 0 as a safe default.

\returns 0 if there is no vertical retrace synchronization, 1 if the buffer swap is synchronized with the vertical retrace, and -1 if late swaps happen immediately instead of waiting for the next retrace; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
