.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 \fBform_driver\fR.
-
+.PP
The function \fBset_field_init\fR sets a hook to be called at form-post time
and each time the selected field changes (after the change). \fBfield_init\fR
returns the current field init hook, if any (\fBNULL\fR if there is no such
hook).
-
+.PP
The function \fBset_field_term\fR sets a hook to be called at form-unpost time
and each time the selected field changes (before the change). \fBfield_term\fR
returns the current field term hook, if any (\fBNULL\fR if there is no such
hook).
-
+.PP
The function \fBset_form_init\fR sets a hook to be called at form-post time and
just after a page change once it is posted. \fBform_init\fR returns the
current form init hook, if any (\fBNULL\fR if there is no such hook).
