NAME
form_field - make and break connections between fields and forms
SYNOPSIS
#include <form.h>
int set_form_fields(FORM *form, FIELD **fields);
FIELD **form_fields(const FORM *form);
int field_count(const FORM *form);
int move_field(FIELD *field, int frow, int fcol);
DESCRIPTION
The function set_form_fields changes the field pointer array of the
given form. The array must be terminated by a NULL.
The function form_fields returns the field array of the given form.
The function field_count returns the count of fields in form.
The function move_field moves the given field (which must be discon-
nected) to a specified location on the screen.
RETURN VALUE
The function form_fields returns a pointer (which may be NULL). It
does not set errno.
The function field_count returns ERR if the form parameter is NULL.
The functions set_form_fields and move_field return one of the follow-
ing codes on error:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_CONNECTED
The field is already connected to a form.
E_POSTED
The form is already posted.
E_SYSTEM_ERROR
System error occurred (see errno(3)).
SEE ALSO
ncurses(3NCURSES), form(3FORM).
NOTES
The header file <form.h> automatically includes the header file
<curses.h>.
PORTABILITY
These routines emulate the System V forms library. They were not sup-
ported on Version 7 or BSD versions.
The SVr4 forms library documentation specifies the field_count error
value as -1 (which is the value of ERR).
