stdscr
or of the
specified window.
The clear
() and
erase
() functions erase all characters on
stdscr
. These differ in that
clear
() uses clearok
() to
force a complete redraw on the next refresh, and
erase
() does not. wclear
()
and werase
() perform the same function as
clear
() 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
.
NULL
if an
error is detected. The functions that return an int will return one of the
following values:
OK
