8.9 Clear Window and Lines int erase()   int werase(win)   werase(...) and erase() will copy blanks to every position on the window win or . For instance, when you set color attributes to a window and call werase() the window would be colored. I had some problems with COLOR_PAIRS when I defined other attributes then black on white so I wrote my own erase function (this is a low level access to the WINDOW structure): The problem is, that ncurses sometimes makes no use of the window attributes when blanking the screen. For instance, in _clrtoeol.c, is BLANK defined as so that the other window attributes get lost while the line is erased. int clear()   int wclear(win)   The same as erase(), but will also set clearok() (the screen will be cleared with the next refresh). int clrtobot()   int wclrtobot(win)   Clearing the current cursor line (start is one character right from the cursor) and the line below the cursor. int clrtoeol()   int wclrtoeol(win)   Clear the current line right from the cursor up to its end.
