curs_scanw(3) curs_scanw(3)
NAME
scanw, wscanw, mvscanw, mvwscanw, vwscanw - convert for-
matted input from a curses widow
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 vwscanw(WINDOW *win, char *fmt, va_list varglist);
DESCRIPTION
The scanw, wscanw and mvscanw routines are analogous to
scanf [see scanf(3)]. The effect of these routines is as
though wgetstr were called on the window, and the result-
ing 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 per-
forms 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 func-
tions. The function vwscanw is marked TO BE WITHDRAWN,
and is to be replaced by a function vw_scanw using the
<stdarg.h> interface.
