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

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).
