DESCRIPTION    [Toc]    [Back]

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

       The  clear  and  wclear  routines are similar to erase and
       werase but also call  clearok.  The  result  is  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.  In addition, these routines
       erase the current line to the right of the cursor, including
 the character on which the cursor is positioned.

       The clrtoeol and wclrtoeol routines erase the current line
       to the right of the cursor,  including  the  character  on
       which the cursor is positioned.

NOTES    [Toc]    [Back]

       The  header  file  <curses.h>  automatically  includes the
       header file <stdio.h>.

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

RETURN VALUES    [Toc]    [Back]

       Upon successful completion, these routines return OK; otherwise,
 they return ERR.
