DESCRIPTION
These functions clear all or part ofstdscr or of the
specified window.
The
clear() and
erase()
functions erase all characters on stdscr.
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.
RETURN VALUES
Functions returning pointers will return
NULL if an error is detected. The functions that
return an int will return one of the following values:
OK- The function completed successfully.
ERR- An error occurred in the function.
