</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       The  function  <STRONG>set_current_field</STRONG>  sets  the  current field of the given
       form; <STRONG>current_field</STRONG> returns the current field of the given form.

       The function <STRONG>unfocus_current_field</STRONG> removes the focus from  the  current
       field  of  the  form.  In such state, inquiries via <STRONG>current_field</STRONG> shall
       return a NULL pointer.

       The function <STRONG>set_form_page</STRONG> sets the form's page number (goes to page  <EM>n</EM>
       of the form).

       The function <STRONG>form_page</STRONG> returns the form's current page number.

       The  function  <STRONG>field_index</STRONG>  returns the index of the field in the field
       array of the form it is connected to.  It returns <STRONG>ERR</STRONG> if  the  argument
       is the null pointer or the field is not connected.


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       Except for <STRONG>form_page</STRONG>, each routine returns one of the following:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_BAD_ARGUMENT</STRONG>
            Routine detected an incorrect or out-of-range argument.

       <STRONG>E_BAD_STATE</STRONG>
            Routine was called from an initialization or termination function.

       <STRONG>E_INVALID_FIELD</STRONG>
            Contents of a field are not valid.

       <STRONG>E_REQUEST_DENIED</STRONG>
            The form driver could not process the request.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno(3)</STRONG>).

       These routines emulate the System  V  forms  library.   They  were  not
       supported on Version 7 or BSD versions.

       The <STRONG>unfocus_current_field</STRONG> function is an ncurses extension.
