Function gdk::error_trap_pop
source · [−]pub fn error_trap_pop() -> i32
Expand description
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
