Not that I know of.

It literally is, in the case of users of GDK.

Nope, GTK simply does this:

  if (wl_display_flush (display->wl_display) < 0)
    {
      g_message ("Error flushing display: %s", g_strerror (errno));
      _exit (1);
    }

if (for example) wl_display_flush, a low-level Wayland interface, fails
from an IO error.
