 CURS_SCANW 3CURSES "Dec 31, 1996"
 NAME
curs_scanw, scanw, wscanw, mvscanw, mvwscanw, vwscanw - convert formatted
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.
