NAME
      cursclear:  erase, werase, clear, wclear, clrtobot, wclrtobot, 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 completely 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.
