    form_field(3x)                                           form_field(3x)

## 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 disconnected) 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 following codes on error:

           E_OK The routine succeeded.

           E_BAD_ARGUMENT
                Routine detected an incorrect or  out-of-range  argu-
                ment.

           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).

## SEE ALSO

           curses(3x), form(3x).

## 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 supported 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).
