NAME
     curs_clear:  erase, werase, clear, wclear, clrtobot, wclrto-
     bot, clrtoeol, wclrtoeol - clear all or part of a curses
     window

SYNOPSIS
     # include <curses.h>

     int erase(void);
     int werase(WINDOW *win);
     int clear(void);
     int wclear(WINDOW *win);
     int clrtobot(void);
     int wclrtobot(WINDOW *win);
     int clrtoeol(void);
     int wclrtoeol(WINDOW *win);

DESCRIPTION
     The erase and werase routines copy blanks to every position
     in the window.

     The clear and wclear routines are like erase and werase, but
     they also call clearok, so that the screen is cleared com-
     pletely on the next call to wrefresh for that window and
     repainted from scratch.

     The clrtobot and wclrtobot routines erase all lines below
     the cursor in the window.  Also, the current line to the
     right of the cursor, inclusive, is erased.

     The clrtoeol and wclrtoeol routines erase the current line
     to the right of the cursor, inclusive.

RETURN VALUE
     All routines return the integer OK, or a non-negative
     integer if immedok is set.

NOTES
     The header file <curses.h> automatically includes the header
     files <stdio.h> and <unctrl.h>.

     Note that erase, werase, clear, wclear, clrtobot, and
     clrtoeol may be macros.
