</PRE>
<H2>NAME</H2><PRE>
       <STRONG>form_field</STRONG> - make and break connections between fields and
       forms


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;form.h&gt;</STRONG>
       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);


</PRE>
<H2>DESCRIPTION</H2><PRE>
       The function <STRONG>set_form_fields</STRONG>  changes  the  field  pointer
       array  of the given <EM>form</EM>.  The array must be terminated by
       a <STRONG>NULL</STRONG>.

       The function <STRONG>form_fields</STRONG> returns the field  array  of  the
       given form.

       The  function  <STRONG>field_count</STRONG>  returns the count of fields in
       <EM>form</EM>.

       The function <STRONG>move_field</STRONG> moves the given field (which  must
       be disconnected) to a specified location on the screen.


</PRE>
<H2>RETURN VALUES</H2><PRE>
       The  function  <STRONG>form_fields</STRONG> returns a pointer (which may be
       <STRONG>NULL</STRONG>).  It does not set errno.

       The function <STRONG>field_count</STRONG> returns <STRONG>ERR</STRONG> if the <EM>form</EM> parameter
       is <STRONG>NULL</STRONG>.

       The functions <STRONG>set_form_fields</STRONG> and <STRONG>move_field</STRONG> return one of
       the following codes on error:

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

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

       <STRONG>E_CONNECTED</STRONG>
            The field is already connected to a form.

       <STRONG>E_POSTED</STRONG>
            The form is already posted.

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

<H2>NOTES</H2><PRE>
       The header file <STRONG>&lt;form.h&gt;</STRONG> automatically includes the header
       file <STRONG>&lt;curses.h&gt;</STRONG>.


</PRE>
<H2>PORTABILITY</H2><PRE>
       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
       <STRONG>field_count</STRONG> error value as -1 (which is the value of <STRONG>ERR</STRONG>).

       curses by Eric S. Raymond.
