651 If an X error occurs which we are not expecting, we have no alternative
|
|
|
652 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
653 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
654 one is not allowed to do any I/O on the display connection from an error
|
|
|
655 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
656
|
|
|
657 However, there are occasions when we might expect an error to reasonably
|
|
|
658 occur. The interface to this is as follows:
|
|
|
659
|
|
|
660 Before calling some X routine which may error, call
|
|
|
661 expect_x_error (dpy);
|
|
|
662
|
|
|
663 Just after calling the X routine, call either:
|
|
|
664
|
|
|
665 x_error_occurred_p (dpy);
|
|
|
666
|
|
|
667 to ask whether an error happened (and was ignored), or:
|
|
|
668
|
|
|
669 signal_if_x_error (dpy, resumable_p);
|
|
|
670
|
|
|
671 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
672 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
673 continue from the call to signal.)
|
|
|
674
|
|
|
675 You must call one of these two routines immediately after calling the X
|
|
|
676 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

1052 The third arg should be one of the symbols 'string, 'integer, 'natnum, or

1053 'boolean, specifying the type of object that the database is searched for.
