int wresize(WINDOW *win, int lines, int columns);
The function returns the integer ERR upon failure and OK on success. It will fail if either of the dimensions less than or equal to zero, or if an error occurs while (re)allocating memory for the window.
The only restriction placed on the dimensions is that they
be greater than zero. The dimensions are not compared to
curses screen dimensions to simplify the logic of
Thomas Dickey (from an equivalent function written in 1988 for BSD curses).
