curs_scanw(3CURSES)	   Curses Library Functions	   curs_scanw(3CURSES)

NAME
       curs_scanw, scanw, wscanw, mvscanw, mvwscanw, vwscanw - convert format-
       ted input from a	curses widow

SYNOPSIS
       cc [ flag ... ] file ...	-lcurses [ library ... ]
       #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 vwscanw(WINDOW *win,	char *fmt, va_list varglist);

DESCRIPTION
       The scanw(), wscanw(), and mvscanw()  routines  correspond  to  scanf()
       (see  scanf(3C)).  The  effect of these routines	is as though wgetstr()
       were called on the window, and the resulting line used as input for the
       scan. 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 VALUES
       vwscanw()  returns ERR on failure and an	integer	equal to the number of
       fields scanned on success.

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