32 .SH NAME
33 \fBset_form_opts\fP,
34 \fBform_opts_on\fP,
35 \fBform_opts_off\fP,
36 \fBform_opts\fR \- set and get form options
37 .SH SYNOPSIS
38 \fB#include <form.h>\fR
39 .br
40 int set_form_opts(FORM *form, Field_Options opts);
41 .br
42 int form_opts_on(FORM *form, Field_Options opts);

44 int form_opts_off(FORM *form, Field_Options opts);
45 .br
46 Field_Options form_opts(const FORM *form);

48 .SH DESCRIPTION
49 The function \fBset_form_opts\fR sets all the given form's option bits (form
50 option bits may be logically-OR'ed together).
51 .PP
52 The function \fBform_opts_on\fR turns on the given option bits, and leaves
53 others alone.
54 .PP
55 The function \fBform_opts_off\fR turns off the given option bits, and leaves
56 others alone.
57 .PP
58 The function \fBform_opts\fR returns the form's current option bits.
59 .PP
60 The following options are defined (all are on by default):
61 .TP 5
62 O_NL_OVERLOAD
63 Overload the \fBREQ_NEW_LINE\fR forms driver request so that calling it at the
64 end of a field goes to the next field.
65 .TP 5
66 O_BS_OVERLOAD
67 Overload the \fBREQ_DEL_PREV\fR forms driver request so that calling it at the
68 beginning of a field goes to the previous field.
69 .SH RETURN VALUE
70 Except for \fBform_opts\fR, each routine returns one of the following:
71 .TP 5
72 .B E_OK
73 The routine succeeded.
74 .TP 5
75 .B E_SYSTEM_ERROR
76 System error occurred (see \fBerrno\fR).
77 .SH SEE ALSO
78 \fBcurses\fR(3X), \fBform\fR(3X).
79 .SH NOTES
80 The header file \fB<form.h>\fR automatically includes the header file
81 \fB<curses.h>\fR.
82 .SH PORTABILITY
83 These routines emulate the System V forms library. They were not supported on
84 Version 7 or BSD versions.
