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 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 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>.
