NAME
     form_field - make and break connections between  fields  and
     forms

SYNOPSIS
     #include 
     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 VALUES
     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 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).

NOTES
     The header file  automatically includes  the  header
     file .

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).
