The

and
erase(
)
functions erase all characters on

perform the same function as

and
erase(

respectively, excepting that the specified window is cleared.
By setting
flag
to
TRUE
,
the
clearok()
function is used to force the next call to
wrefresh(
)
to clear and completely redraw the window given in
win
.
The function
clrtobot()
will clear
stdscr
from the current row to the bottom of the screen.
clrtoeol()
will clear
stdscr
from the current column position to the end of the line.
wclrtobot()
and
wclrtoeol(
)
are the same as
clrtobot(
)
and
clrtoeol(
),
respectively, excepting the window specified is operated on instead of
stdscr
.

if an error is detected.
