form_field(3X)							form_field(3X)

NAME
       form_field - make and break connections between fields and forms

SYNOPSIS
       #include	<form.h>
       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  discon-
       nected) to a specified location on the screen.

RETURN VALUE
       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).

SEE ALSO
       curses(3X), form(3X).

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

PORTABILITY
       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).
