    window: *mut SDL_Window,
) -> bool

Expand description

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.

§Parameters

  • window: the window to change.

§Return value

Returns true on success or false on failure; call SDL_GetError() for more information.

§Thread safety

This function should only be called on the main thread.

§Availability

This function is available since SDL 3.2.0.
