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 previous 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.
