466 If an X error occurs which we are not expecting, we have no alternative
|
|
|
467 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
468 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
469 one is not allowed to do any I/O on the display connection from an error
|
|
|
470 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
471
|
|
|
472 However, there are occasions when we might expect an error to reasonably
|
|
|
473 occur. The interface to this is as follows:
|
|
|
474
|
|
|
475 Before calling some X routine which may error, call
|
|
|
476 expect_x_error (dpy);
|
|
|
477
|
|
|
478 Just after calling the X routine, call either:
|
|
|
479
|
|
|
480 x_error_occurred_p (dpy);
|
|
|
481
|
|
|
482 to ask whether an error happened (and was ignored), or:
|
|
|
483
|
|
|
484 signal_if_x_error (dpy, resumable_p);
|
|
|
485
|
|
|
486 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
487 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
488 continue from the call to signal.)
|
|
|
489
|
|
|
490 You must call one of these two routines immediately after calling the X
|
|
|
491 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

|

941 returned value is the list (t) for true, (nil) for false, and is nil to

942 mean ``unspecified.''
