Function sdl2_sys::SDL_GL_SwapWindow

pub unsafe extern "C" fn SDL_GL_SwapWindow(window: *mut SDL_Window)

Update a window with OpenGL rendering.

This is used with double-buffered OpenGL contexts, which are the default.

On macOS, make sure you bind 0 to the draw framebuffer before swapping the window, otherwise nothing will happen. If you aren’t using glBindFramebuffer(), this is the default and you won’t have to do anything extra.

\param window the window to change

\since This function is available since SDL 2.0.0.
