NAME
clear, erase, wclear, werase — clear a window
SYNOPSIS
#include <curses.h>
int clear(void);
int erase(void);
int wclear(WINDOW *win);
int werase(WINDOW *win);
DESCRIPTION
The
clear(),
erase(),
wclear()
and
werase()
functions clear every position in the current or specified window.
The
clear()
and
wclear()
functions also achieve the same effect as calling
clearok(),
so that the window is cleared completely on the next call to
wrefresh()
for the window and is redrawn in its entirety.
RETURN VALUE
Upon successful completion, these functions return OK.
Otherwise, they return ERR.
ERRORS
No errors are defined.
CHANGE HISTORY

and

functions is explicitly declared as void.
