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.
SEE ALSO
clearok(3X), doupdate(3X), <curses.h>.
CHANGE HISTORY
First released in X/Open Curses, Issue 2.
X/Open Curses, Issue 4
The erase() and werase() functions are merged with this entry. In previous issues, they appeared in
entries of their own.
The entry is rewritten for clarity. The argument list for the clear() and erase() functions is expli-
citly declared as void.
