The user need not specify any application-defined initialization or termination routines at all, but they may be helpful for displaying messages or page numbers and other chores. .sp .LP \fBset_form_init()\fR assigns an application-defined initialization function to be called when the \fIform\fR is posted and just after a page change. \fBform_init()\fR returns a pointer to the initialization function, if any. .sp .LP \fBset_form_term()\fR assigns an application-defined function to be called when the \fIform\fR is unposted and just before a page change. \fBform_term()\fR returns a pointer to the function, if any. .sp .LP \fBset_field_init()\fR assigns an application-defined function to be called when the \fIform\fR is posted and just after the current field changes. \fBfield_init()\fR returns a pointer to the function, if any. .sp .LP \fBset_field_term()\fR assigns an application-defined function to be called when the \fIform\fR is unposted and just before the current field changes. \fBfield_term()\fR returns a pointer to the function, if any. .SH RETURN VALUES .sp .LP Routines that return pointers always return \fINULL\fR on error. Routines that return an integer return one of the following: .sp .ne 2 .mk .na \fBE_OK\fR .ad .RS 18n .rt The function returned successfully. .RE .sp .ne 2 .mk .na \fBE_SYSTEM_ERROR\fR .ad .RS 18n .rt System error. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
