|
|
|
726
|
|
|
727 If an X error occurs which we are not expecting, we have no alternative
|
|
|
728 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
729 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
730 one is not allowed to do any I/O on the display connection from an error
|
|
|
731 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
732
|
|
|
733 However, there are occasions when we might expect an error to reasonably
|
|
|
734 occur. The interface to this is as follows:
|
|
|
735
|
|
|
736 Before calling some X routine which may error, call
|
|
|
737 expect_x_error (dpy);
|
|
|
738
|
|
|
739 Just after calling the X routine, call either:
|
|
|
740
|
|
|
741 x_error_occurred_p (dpy);
|
|
|
742
|
|
|
743 to ask whether an error happened (and was ignored), or:
|
|
|
744
|
|
|
745 signal_if_x_error (dpy, resumable_p);
|
|
|
746
|
|
|
747 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
748 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
749 continue from the call to signal.)
|
|
|
750
|
|
|
751 You must call one of these two routines immediately after calling the X
|
|
|
752 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.
