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 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.

NOTES



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).
