602 If an X error occurs which we are not expecting, we have no alternative
|
|
|
603 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
604 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
605 one is not allowed to do any I/O on the display connection from an error
|
|
|
606 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
607
|
|
|
608 However, there are occasions when we might expect an error to reasonably
|
|
|
609 occur. The interface to this is as follows:
|
|
|
610
|
|
|
611 Before calling some X routine which may error, call
|
|
|
612 expect_x_error (dpy);
|
|
|
613
|
|
|
614 Just after calling the X routine, call either:
|
|
|
615
|
|
|
616 x_error_occurred_p (dpy);
|
|
|
617
|
|
|
618 to ask whether an error happened (and was ignored), or:
|
|
|
619
|
|
|
620 signal_if_x_error (dpy, resumable_p);
|
|
|
621
|
|
|
622 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
623 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
624 continue from the call to signal.)
|
|
|
625
|
|
|
626 You must call one of these two routines immediately after calling the X
|
|
|
627 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.
