676 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
677
|
|
|
678 However, there are occasions when we might expect an error to reasonably
|
|
|
679 occur. The interface to this is as follows:
|
|
|
680
|
|
|
681 Before calling some X routine which may error, call
|
|
|
682 expect_x_error (dpy);
|
|
|
683
|
|
|
684 Just after calling the X routine, call either:
|
|
|
685
|
|
|
686 x_error_occurred_p (dpy);
|
|
|
687
|
|
|
688 to ask whether an error happened (and was ignored), or:
|
|
|
689
|
|
|
690 signal_if_x_error (dpy, resumable_p);
|
|
|
691
|
|
|
692 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
693 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
694 continue from the call to signal.)
|
|
|
695
|
|
|
696 You must call one of these two routines immediately after calling the X
|
|
|
697 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.
