this function is an internal one, used to setup the main gdk/gtk loop.
to catch X errors for certain code portions (once you figured *why* 
you are getting the error and have ensured that there is actually no way
to fix your code and work around that) you should use:

gdk_error_trap_push ();

/* call possibly offensive function here */
gdk_sync(); /* flush the x queue to catch errors now */

if (gdk_error_trap_pop ())
  /* handle error case */;
