418 If an X error occurs which we are not expecting, we have no alternative
|
|
|
419 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
420 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
421 one is not allowed to do any I/O on the display connection from an error
|
|
|
422 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
423
|
|
|
424 However, there are occasions when we might expect an error to reasonably
|
|
|
425 occur. The interface to this is as follows:
|
|
|
426
|
|
|
427 Before calling some X routine which may error, call
|
|
|
428 expect_x_error (dpy);
|
|
|
429
|
|
|
430 Just after calling the X routine, call either:
|
|
|
431
|
|
|
432 x_error_occurred_p (dpy);
|
|
|
433
|
|
|
434 to ask whether an error happened (and was ignored), or:
|
|
|
435
|
|
|
436 signal_if_x_error (dpy, resumable_p);
|
|
|
437
|
|
|
438 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
439 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
440 continue from the call to signal.)
|
|
|
441
|
|
|
442 You must call one of these two routines immediately after calling the X
|
|
|
443 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

804 The second arg is the class of the resource to retrieve, like \"Font\".
|

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

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

880 mean ``unspecified.''
