error_trap_pop

Removes an error trap pushed with error_trap_push.

May block until an error has been definitively received or not received from the X server. error_trap_pop_ignored is preferred if you don’t need to know whether an error occurred, because it never has to block. If you don't need the return value of error_trap_pop, use error_trap_pop_ignored.

Prior to GDK 3.0, this function would not automatically sync for you, so you had to flush if your last call to Xlib was not a blocking round trip.

Returns:

X error code or 0 on success
