Function winit::platform::unix::register_xlib_error_hook

pub fn register_xlib_error_hook(hook: XlibErrorHook)

Hook to winit’s xlib error handling callback.

This method is provided as a safe way to handle the errors comming from X11 when using xlib in external crates, like glutin for GLX access. Trying to handle errors by speculating with XSetErrorHandler is unsafe.
