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.
