curs_scanw(3)

NAME
scanw, wscanw, mvscanw, mvwscanw, vwscanw - convert formatted input from a ncurses widow

SYNOPSIS
#include <ncurses.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 resulting 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 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 use the return value from the scanw, wscanw, mvscanw and mvwscanw routines to determine the number of fields which were mapped in the call.
