.SH NAME
\fBform_opts\fR - set and get form options
.SH SYNOPSIS
\fB#include <form.h>\fR
.br
int set_form_opts(FORM *form, Field_Options opts);
.br
int form_opts_on(FORM *form, Field_Options opts);
.br
int form_opts_off(FORM *form, Field_Options opts);
.br
Field_Options form_opts(const FORM *form);
.br
.SH DESCRIPTION
The function \fBset_form_opts\fR sets all the given form's option bits (form
option bits may be logically-OR'ed together).
.PP
The function \fBform_opts_on\fR turns on the given option bits, and leaves
others alone.
.PP
The function \fBform_opts_off\fR turns off the given option bits, and leaves
others alone.
.PP
The function \fBform_opts\fR returns the form's current option bits.
.PP
The following options are defined (all are on by default):
.TP 5
O_NL_OVERLOAD
Overload the \fBREQ_NEW_LINE\fR forms driver request so that calling it at the
end of a field goes to the next field.
.TP 5
O_BS_OVERLOAD
Overload the \fBREQ_DEL_PREV\fR forms driver request so that calling it at the
beginning of a field goes to the previous field.
.SH RETURN VALUE
Except for \fBform_opts\fR, each routine returns one of the following:
.TP 5
.B E_OK
The routine succeeded.
.TP 5
.B E_SYSTEM_ERROR
System error occurred (see \fBerrno\fR).
.SH SEE ALSO
\fBcurses\fR(3X), \fBform\fR(3X).
.SH NOTES
The header file \fB<form.h>\fR automatically includes the header file
\fB<curses.h>\fR.
.SH PORTABILITY
These routines emulate the System V forms library.  They were not supported on
Version 7 or BSD versions.
