scanw, wscanw, mvscanw, mvwscanw, vwscanw - convert formatted input
from a curses widow
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);
The scanw, wscanw and mvscanw routines are analogous 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
sscanf(3). Fields which do not map to a variable in the fmt field are
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>.
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.
The XSI Curses standard, Issue 4 describes these functions. The func‐
tion vwscanw is marked TO BE WITHDRAWN, and is to be replaced by a
function vw_scanw using the <stdarg.h> interface.
