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 VALUES
All routines return the integer
OK, or a non-negative integer if
immedok() is set. See
curs_outopts(3CURSES).
