<H2>NAME</H2><PRE>
<B>form_field</B> - make and break connections between fields and
forms
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>#include</B> <B><form.h></B>
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 <B>set_form_fields</B> changes the field pointer
array of the given <I>form</I>. The array must be terminated by
a <B>NULL</B>.
The function <B>form_fields</B> returns the field array of the
given form.
The function <B>field_count</B> returns the count of fields in
<I>form</I>.
The function <B>move_field</B> move the given field (which must
be disconnected) to a specified location on the screen.
</PRE>
<H2>RETURN VALUES</H2><PRE>
The function <B>form_fields</B> returns <B>NULL</B> on error.
The function <B>field_count</B> returns <B>ERR</B> (the general <B>curses</B>
error return value) on error.
The functions <B>set_form_fields</B> and <B>move_field</B> return one of
the following codes on error:
<B>E_OK</B> The routine succeeded.
<B>E_SYSTEM_ERROR</B>
System error occurred (see <B>errno</B>).
<B>E_BAD_ARGUMENT</B>
Routine detected an incorrect or out-of-range argu-
ment.
<B>E_POSTED</B>
The form is already posted.
<B>E_CONNECTED</B>
The field is already connected to a form.
</PRE>
<H2>SEE ALSO</H2><PRE>
<B><A HREF="ncurses.3x.html">curses(3x)</A></B>, <B><A HREF="form.3x.html">form(3x)</A></B>.
</PRE>
<H2>NOTES</H2><PRE>
The header file <B><form.h></B> automatically includes the header
file <B><curses.h></B>.
</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
<B>field_count</B> error value as -1 (which is the value of <B>ERR</B>).
