880 If an X error occurs which we are not expecting, we have no alternative
|
|
|
881 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
882 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
883 one is not allowed to do any I/O on the display connection from an error
|
|
|
884 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
885
|
|
|
886 However, there are occasions when we might expect an error to reasonably
|
|
|
887 occur. The interface to this is as follows:
|
|
|
888
|
|
|
889 Before calling some X routine which may error, call
|
|
|
890 expect_x_error (dpy);
|
|
|
891
|
|
|
892 Just after calling the X routine, call either:
|
|
|
893
|
|
|
894 x_error_occurred_p (dpy);
|
|
|
895
|
|
|
896 to ask whether an error happened (and was ignored), or:
|
|
|
897
|
|
|
898 signal_if_x_error (dpy, resumable_p);
|
|
|
899
|
|
|
900 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
901 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
902 continue from the call to signal.)
|
|
|
903
|
|
|
904 You must call one of these two routines immediately after calling the X
|
|
|
905 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.
