.SH SYNOPSIS
|
|
\fB#include <form.h>\fR
|

|
|
\fBint set_form_fields(FORM *\fP\fIform\fP\fB, FIELD **\fP\fIfields\fP\fB);\fP

.SH DESCRIPTION
|
|
The function \fBset_form_fields\fR changes the field pointer array of
|
|
the given \fIform\fR. The array must be terminated by a \fBNULL\fR.
|
|
.PP
|
|
The function \fBform_fields\fR returns the field array of the given form.
|
|
.PP
|
|
The function \fBfield_count\fR returns the count of fields in \fIform\fR.
|
|
.PP
|
|
The function \fBmove_field\fR moves the given field (which must be disconnected)
|
|
to a specified location on the screen.
|
|
.SH RETURN VALUE
|
|
The function \fBform_fields\fR returns a pointer (which may be \fBNULL\fR).
|
|
It does not set \fBerrno\fP.
|
|
.PP
|
|
The function \fBfield_count\fR returns \fBERR\fR if the \fIform\fP parameter
|
|
is \fBNULL\fP.
|
|
.PP
|
|
The functions \fBset_form_fields\fR and \fBmove_field\fR return one of
|
|
the following codes on error:
|
|
.TP 5
|
|
.B E_OK
|
|
The routine succeeded.
|
|
.TP 5
|
|
.B E_BAD_ARGUMENT
|
|
Routine detected an incorrect or out-of-range argument.
|
|
.TP 5
|
|
.B E_CONNECTED
|
|
The field is already connected to a form.
|
|
.TP 5
|
|
.B E_POSTED
|
|
The form is already posted.
|
|
.TP 5
|
|
.B E_SYSTEM_ERROR
|
|

|
|
.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.
|
|
.PP

|
The SVr4 forms library documentation specifies the \fBfield_count\fR error value
|
|
as \-1 (which is the value of \fBERR\fR).
