curs_scanw(3)					    curs_scanw(3)

NAME
       scanw,  wscanw,	mvscanw, mvwscanw, vwscanw - convert for-
       matted 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  are  analogous  to
       scanf [see scanf(3S)].  The effect of these routines is as
       though wgetstr were called on the window, and the  result-
       ing 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 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 use the	 return	 value	from  the  scanw,
       wscanw,	mvscanw	 and  mvwscanw	routines to determine the
       number of fields which were mapped in the call.

PORTABILITY
       The XSI Curses standard, Issue  4  describes  these  func-
       tions.	The  function  vwscanw is marked TO BE WITHDRAWN,
       and is to be replaced by a  function  vw_scanw  using  the
       <stdarg.h> interface.
