962 If an X error occurs which we are not expecting, we have no alternative
|
|
|
963 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
964 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
965 one is not allowed to do any I/O on the display connection from an error
|
|
|
966 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
967
|
|
|
968 However, there are occasions when we might expect an error to reasonably
|
|
|
969 occur. The interface to this is as follows:
|
|
|
970
|
|
|
971 Before calling some X routine which may error, call
|
|
|
972 expect_x_error (dpy);
|
|
|
973
|
|
|
974 Just after calling the X routine, call either:
|
|
|
975
|
|
|
976 x_error_occurred_p (dpy);
|
|
|
977
|
|
|
978 to ask whether an error happened (and was ignored), or:
|
|
|
979
|
|
|
980 signal_if_x_error (dpy, resumable_p);
|
|
|
981
|
|
|
982 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
983 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
984 continue from the call to signal.)
|
|
|
985
|
|
|
986 You must call one of these two routines immediately after calling the X
|
|
|
987 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

1435 `integer', an integer is returned. If the third arg is `boolean', then the

1436 returned value is the list (t) for true, (nil) for false, and is nil to

1437 mean ``unspecified''.
