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