<B>scanw</B>, <B>wscanw</B>, <B>mvscanw</B>, <B>mvwscanw</B>, <B>vwscanw</B>, <B>vw_scanw</B> - con-
vert formatted input from a <B>curses</B> window
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>#include</B> <B><curses.h></B>
<B>int</B> <B>scanw(char</B> <B>*fmt</B> [<B>,</B> <B>arg</B>] <B>...);</B>
<B>int</B> <B>wscanw(WINDOW</B> <B>*win,</B> <B>char</B> <B>*fmt</B> [<B>,</B> <B>arg</B>] <B>...);</B>

<B>int</B> <B>mvwscanw(WINDOW</B> <B>*win,</B> <B>int</B> <B>y,</B> <B>int</B> <B>x,</B>
<B>char</B> <B>*fmt</B> [<B>,</B> <B>arg]</B> <B>...);</B>
<B>int</B> <B>vw_scanw(WINDOW</B> <B>*win,</B> <B>char</B> <B>*fmt,</B> <B>va_list</B> <B>varglist);</B>
<B>int</B> <B>vwscanw(WINDOW</B> <B>*win,</B> <B>char</B> <B>*fmt,</B> <B>va_list</B> <B>varglist);</B>
</PRE>
<H2>DESCRIPTION</H2><PRE>
The <B>scanw</B>, <B>wscanw</B> and <B>mvscanw</B> routines are analogous to
<B>scanf</B> [see <B><A HREF="scanf.3S.html">scanf(3S)</A></B>]. The effect of these routines is as
though <B>wgetstr</B> were called on the window, and the result-
ing line used as input for <B><A HREF="sscanf.3.html">sscanf(3)</A></B>. Fields which do not
map to a variable in the <I>fmt</I> field are lost.
The <B>vwscanw</B> routine is similar to <B>vwprintw</B> in that it per-
forms a <B>wscanw</B> using a variable argument list. The third
argument is a <I>va</I>_<I>list</I>, a pointer to a list of arguments,
as defined in <B><varargs.h></B>.
</PRE>
<H2>RETURN VALUE</H2><PRE>
<B>vwscanw</B> returns <B>ERR</B> on failure and an integer equal to the
number of fields scanned on success.
Applications may use the return value from the <B>scanw</B>,
<B>wscanw</B>, <B>mvscanw</B> and <B>mvwscanw</B> routines to determine the
number of fields which were mapped in the call.
</PRE>
<H2>PORTABILITY</H2><PRE>
The XSI Curses standard, Issue 4 describes these func-
tions. The function <B>vwscanw</B> is marked TO BE WITHDRAWN,
and is to be replaced by a function <B>vw_scanw</B> using the
<B><stdarg.h></B> interface.
