curs_clear(3X)                                               curs_clear(3X)


   NAME
         curs_clear:  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.
