.SH DESCRIPTION
These functions make it possible to set hook functions to be called at various
points in the automatic processing of input event codes by \fBmenu_driver\fR.
-
+.PP
The function \fBset_item_init\fR sets a hook to be called at menu-post time and
each time the selected item changes (after the change). \fBitem_init\fR
returns the current item init hook, if any (\fBNULL\fR if there is no such
hook).
-
+.PP
The function \fBset_item_term\fR sets a hook to be called at menu-unpost time
and each time the selected item changes (before the change). \fBitem_term\fR
returns the current item term hook, if any (\fBNULL\fR if there is no such
hook).
-

The function \fBset_menu_init\fR sets a hook to be called at menu-post time and
just after the top row on the menu changes once it is posted. \fBmenu_init\fR
returns the current menu init hook, if any (\fBNULL\fR if there is no such
hook).
