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, excepting 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.
