CURSES_CLEAR(3) 		   BSD Library Functions Manual 		  CURSES_CLEAR(3)

NAME
     curses_clear, clear, wclear, clearok, clrtobot, clrtoeol, erase, werase, wclrtobot,
     wclrtoeol -- curses clear window routines

LIBRARY
     Curses Library (libcurses, -lcurses)

SYNOPSIS
     #include <curses.h>

     int
     clear(void);

     int
     clearok(WINDOW *win, bool flag);

     int
     clrtobot(void);

     int
     clrtoeol(void);

     int
     erase(void);

     int
     wclear(WINDOW *win);

     int
     werase(WINDOW *win);

     int
     wclrtobot(WINDOW *win);

     int
     wclrtoeol(WINDOW *win);

DESCRIPTION
     These functions clear all or part of stdscr or of the specified window.

     The clear() and erase() functions erase all characters on stdscr.	wclear() and werase()
     perform the same function as clear() and erase(), respectively, excepting that the specified
     window is cleared.

     By setting flag to TRUE, the clearok() function is used to force the next call to wrefresh()
     to clear and completely redraw the window given in win.

     The function clrtobot() will clear stdscr from the current row to the bottom of the screen.
     clrtoeol() will clear stdscr from the current column position to the end of the line.
     wclrtobot() and wclrtoeol() are the same as clrtobot() and clrtoeol(), respectively, except-
     ing the window specified is operated on instead of stdscr.

RETURN VALUES
     Functions returning pointers will return NULL if an error is detected.  The functions that
     return an int will return one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.

SEE ALSO
     curses_refresh(3)

STANDARDS
     The NetBSD Curses library complies with the X/Open Curses specification, part of the Single
     Unix Specification.

HISTORY
     The Curses package appeared in 4.0BSD.
