480 If an X error occurs which we are not expecting, we have no alternative
|
|
|
481 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
482 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
483 one is not allowed to do any I/O on the display connection from an error
|
|
|
484 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
485
|
|
|
486 However, there are occasions when we might expect an error to reasonably
|
|
|
487 occur. The interface to this is as follows:
|
|
|
488
|
|
|
489 Before calling some X routine which may error, call
|
|
|
490 expect_x_error (dpy);
|
|
|
491
|
|
|
492 Just after calling the X routine, call either:
|
|
|
493
|
|
|
494 x_error_occurred_p (dpy);
|
|
|
495
|
|
|
496 to ask whether an error happened (and was ignored), or:
|
|
|
497
|
|
|
498 signal_if_x_error (dpy, resumable_p);
|
|
|
499
|
|
|
500 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
501 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
502 continue from the call to signal.)
|
|
|
503
|
|
|
504 You must call one of these two routines immediately after calling the X
|
|
|
505 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.
