curs_scanw(3X)                                               curs_scanw(3X)


   NAME
         cursscanw:  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>.
