int vwscanw(WINDOW *win, char *fmt, va_list varglist);
fmt
Is a scanf() format string.
varglist
Is a pointer to a list of parameters.
win
Is a pointer to the window in which the character is to
be read.
The vwscanw() function achieves the same effect as wscanw(3XCURSES)
using a variable argument list. The third argument is a va_list, as
defined in <varargs.h>.
Upon successful completion, vwscanw() returns OK. Otherwise, it
returns ERR.
No errors are defined.
The vwscanw() function is deprecated; the vw_scanw(3XCURSES) function
is preferred. The use of the vwscanw() and vw_scanw() in the same
file will not work, due to the requirements to include <varargs.h>
and <stdarg.h>, which both contain definitions of va_list.

NAME
vwscanw - convert formatted input from a window
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#include <varargs.h>
#include <curses.h>
int vwscanw(WINDOW *win, char *fmt, va_list varglist);
PARAMETERS
fmt
Is a scanf() format string.
varglist
Is a pointer to a list of parameters.
win
Is a pointer to the window in which the character is to
be read.
DESCRIPTION
The vwscanw() function achieves the same effect as wscanw(3XCURSES)
using a variable argument list. The third argument is a va_list, as
defined in <varargs.h>.
RETURN VALUES
Upon successful completion, vwscanw() returns OK. Otherwise, it
returns ERR.
ERRORS
No errors are defined.
USAGE
The vwscanw() function is deprecated; the vw_scanw(3XCURSES) function
is preferred. The use of the vwscanw() and vw_scanw() in the same
file will not work, due to the requirements to include <varargs.h>
and <stdarg.h>, which both contain definitions of va_list.
