1030 /* Handling errors.
|
|
|
1031
|
|
|
1032 If an X error occurs which we are not expecting, we have no alternative
|
|
|
1033 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
1034 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
1035 one is not allowed to do any I/O on the display connection from an error
|
|
|
1036 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
1037
|
|
|
1038 However, there are occasions when we might expect an error to reasonably
|
|
|
1039 occur. The interface to this is as follows:
|
|
|
1040
|
|
|
1041 Before calling some X routine which may error, call
|
|
|
1042 expect_x_error (dpy);
|
|
|
1043
|
|
|
1044 Just after calling the X routine, call either:
|
|
|
1045
|
|
|
1046 x_error_occurred_p (dpy);
|
|
|
1047
|
|
|
1048 to ask whether an error happened (and was ignored), or:
|
|
|
1049
|
|
|
1050 signal_if_x_error (dpy, resumable_p);
|
|
|
1051
|
|
|
1052 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
1053 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
1054 continue from the call to signal.)
|
|
|
1055
|
|
|
1056 You must call one of these two routines immediately after calling the X
|
|
|
1057 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

1438 The second arg is the class of the resource to retrieve, such as "Font".
|
|
3025
|
1439 The third arg must be one of the symbols `string', `integer', `natnum', or
|
|
|
1440 `boolean', specifying the type of object that the database is searched for.
|
|
428
|
1441 The fourth arg is the locale to search for the resources on, and can

3025

1442 currently be a buffer, a frame, a device, or `global'. If omitted, it

|

1478 (x-get-resource "foreground" "Foreground" 'string SOME-FRAME)
|
|
|
1479
|
|
|
1480 is an interface to a C call something like

3025

1506 Note that for `global', no prefix is added other than that of the

1508 arbitrary application resources, if you really want to.

1510 The returned value of this function is nil if the queried resource is not

1512 `integer', an integer is returned. If the third arg is `boolean', then the
|
|
|
1513 returned value is the list (t) for true, (nil) for false, and is nil to
|

430
|
1514 mean ``unspecified''.
