1049 /* Handling errors.
|
|
|
1050
|
|
|
1051 If an X error occurs which we are not expecting, we have no alternative
|
|
|
1052 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
1053 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
1054 one is not allowed to do any I/O on the display connection from an error
|
|
|
1055 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
1056
|
|
|
1057 However, there are occasions when we might expect an error to reasonably
|
|
|
1058 occur. The interface to this is as follows:
|
|
|
1059
|
|
|
1060 Before calling some X routine which may error, call
|
|
|
1061 expect_x_error (dpy);
|
|
|
1062
|
|
|
1063 Just after calling the X routine, call either:
|
|
|
1064
|
|
|
1065 x_error_occurred_p (dpy);
|
|
|
1066
|
|
|
1067 to ask whether an error happened (and was ignored), or:
|
|
|
1068
|
|
|
1069 signal_if_x_error (dpy, resumable_p);
|
|
|
1070
|
|
|
1071 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
1072 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
1073 continue from the call to signal.)
|
|
|
1074
|
|
|
1075 You must call one of these two routines immediately after calling the X
|
|
|
1076 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

1456 The first arg is the name of the resource to retrieve, such as "font".
|

|
1457 The second arg is the class of the resource to retrieve, such as "Font".
|
|
3025
|
1458 The third arg must be one of the symbols `string', `integer', `natnum', or
|
|
|
1459 `boolean', specifying the type of object that the database is searched for.
|
|
428
|
1460 The fourth arg is the locale to search for the resources on, and can
|

3025
|
1461 currently be a buffer, a frame, a device, or `global'. If omitted, it

|

1488

1489 is an interface to a C call something like

1496
|
|
|
1497 (x-get-resource "foreground" "Foreground" 'string SOME-FRAME)
|
|
|
1498
|
|
|
1499 is an interface to a C call something like
|
|
|
1500
|
|
|
1501 XrmGetResource (db, "xemacs.frame.FRAME-NAME.foreground",

3025
|
1525 Note that for `global', no prefix is added other than that of the

1526 application itself; thus, you can use this locale to retrieve

1527 arbitrary application resources, if you really want to.

1528

1529 The returned value of this function is nil if the queried resource is not

1530 found. If the third arg is `string', a string is returned, and if it is

|
1531 `integer', an integer is returned. If the third arg is `boolean', then the
|
|
|
1532 returned value is the list (t) for true, (nil) for false, and is nil to
|
|
430
|
1533 mean ``unspecified''.
