curs_scanw(3X)curs_scanw(3X)NAME
curs_scanw: scanw, wscanw, mvscanw, mvwscanw, vwscanw - convert
formatted 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 correspond 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 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 VALUE
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.
NOTES
The header file <curses.h> automatically includes the header files
<stdio.h> and <unctrl.h>.
