CURS_SCANW(3CURSES) Curses Library Functions CURS_SCANW(3CURSES)
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.
