966 If an X error occurs which we are not expecting, we have no alternative
|
|
|
967 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
968 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
969 one is not allowed to do any I/O on the display connection from an error
|
|
|
970 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
971
|
|
|
972 However, there are occasions when we might expect an error to reasonably
|
|
|
973 occur. The interface to this is as follows:
|
|
|
974
|
|
|
975 Before calling some X routine which may error, call
|
|
|
976 expect_x_error (dpy);
|
|
|
977
|
|
|
978 Just after calling the X routine, call either:
|
|
|
979
|
|
|
980 x_error_occurred_p (dpy);
|
|
|
981
|
|
|
982 to ask whether an error happened (and was ignored), or:
|
|
|
983
|
|
|
984 signal_if_x_error (dpy, resumable_p);
|
|
|
985
|
|
|
986 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
987 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
988 continue from the call to signal.)
|
|
|
989
|
|
|
990 You must call one of these two routines immediately after calling the X
|
|
|
991 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

1354 The fifth arg is the device to search for the resources on. (The resource

1362 The sixth arg NOERROR, if non-nil, means do not signal an error if a

1363 bogus resource specification was retrieved (e.g. if a non-integer was
|
|
|
1364 given when an integer was requested). In this case, a warning is issued

410
