curs_scanw(3)
NAME
  curs_scanw, scanw, wscanw, mvscanw, mvwscanw, vw_scanw, vwscanw - Convert
  formatted input from a Curses window

LIBRARY
  Curses Library (libcurses.a, libcurses.so)

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] ...);

  include <stdarg.h>
  include <curses.h>

  int vw_scanw(WINDOW *win, char *fmt,
	  va_list varglist);

  include <varargs.h>
  include <curses.h>

  int vwscanw(WINDOW *win, char *fmt,
	  va_list varglist);

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  scanw, wscanw, mvscanw, mvwscanw, vw_scanw, vwscanw:	 XPG4-UNIX

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

DESCRIPTION
  The scanw, wscanw, and mvscanw routines correspond to scanf (see
  fscanf(3)).  The effect of these routines is as though wgetstr were called
  on the window, and the resulting line were used as input for the scan.
  Fields that do not map to a variable in the fmt field are lost.

  The vw_scanw routine is similar to vwprintw in that it uses a variable
  argument list.  The third argument is va_list, a pointer to a list of
  arguments, as defined in stdarg.h.

  The vwscanw routine is equivalent to vw_scanw except that va_list is
  defined in varargs.h.	 Use of vw_scanw is recommended for new applications.



NOTES
  The header file curses.h automatically includes the header file stdio.h.

RETURN VALUES
  These routines return ERR on failure and OK upon successful completion.
