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.
