# 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 move the given field  (which  must
           be disconnected) to a specified location on the screen.

## RETURN VALUES

           The function form_fields returns NULL on error.

           The  function  field_count returns ERR (the general curses
           error return value) on error.

           The functions set_form_fields and move_field return one of
           the following codes on error:

           E_OK The routine succeeded.

           E_SYSTEM_ERROR
                System error occurred (see errno).

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

           E_POSTED
                The form is already posted.

           E_CONNECTED
                The field is already connected to a form.

## 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).
