       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.
       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)).

       The  header  file  <form.h>  automatically  includes  the  header  file
       <curses.h>.
       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).
