CLEAR(3XCURSES)						       CLEAR(3XCURSES)

NAME
       clear, erase, wclear, werase - clear a window

SYNOPSIS
       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib \
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int clear(void);

       int erase(void);

       int wclear(WINDOW *win);

       int werase(WINDOW *win);

DESCRIPTION
       The  clear() and erase() functions clear stdscr,	 destroying its previ‐
       ous contents. The wclear() and  werase()	 functions  perform  the  same
       action,	but clear the window specified by win instead of stdscr.

       The  clear()  and  wclear() functions also call the clearok() function.
       This function clears and redraws the entire screen on the next call  to
       refresh(3XCURSES) or wrefresh(3XCURSES) for the window.

       The  current background character (and attributes) is used to clear the
       screen.

PARAMETERS
       win
	      Is a pointer to the window that is to be cleared.

ERRORS
       OK
	      Successful completion.

       ERR
	      An error occurred.
