clear(3XCURSES)		X/Open Curses Library Functions	       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  ac-
       tion,  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.
