NAME
       scanw, wscanw, mvscanw, mvwscanw, vwscanw, vw_scanw - convert formatted input from a curses window

SYNOPSIS
       #include <curses.h>

       int scanw(char *fmt [, arg] ...);
       int wscanw(WINDOW *win, char *fmt [, arg] ...);
       int mvscanw(int y, int x, char *fmt [, arg] ...);
       int mvwscanw(WINDOW *win, int y, int x,
	     char *fmt [, arg] ...);
       int vw_scanw(WINDOW *win, char *fmt, va_list varglist);
       int vwscanw(WINDOW *win, char *fmt, va_list varglist);

DESCRIPTION
       The  scanw,  wscanw  and  mvscanw  routines are analogous to scanf [see scanf(3S)].  The effect of these routines is as though wgetstr were
       called on the window, and the resulting line used as input for sscanf(3).  Fields which do not map to a variable in the fmt field are lost.

       The vwscanw routine is similar to vwprintw in that it performs a wscanw using a variable argument list.	The third argument is a va_list, a
       pointer to a list of arguments, as defined in <varargs.h>.

RETURN VALUE
       vwscanw returns ERR on failure and an integer equal to the number of fields scanned on success.

       Applications  may  use  the return value from the scanw, wscanw, mvscanw and mvwscanw routines to determine the number of fields which were
       mapped in the call.

PORTABILITY
       The XSI Curses standard, Issue 4 describes these functions.  The function vwscanw is marked TO BE WITHDRAWN, and is to  be  replaced  by  a
       function vw_scanw using the <stdarg.h> interface.
