wresize - resize a curses window
int wresize(WINDOW *win, int lines, int columns);
The wresize function reallocates storage for an ncurses window to adjust its dimensions to
the specified values. If either dimension is larger than the current values, the window's
data is filled with blanks that have the current background rendition (as set by wbkgnd-
set) merged into them.
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)allo-
cating 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
resizeterm. The caller must ensure that the window's dimensions fit within the actual
Thomas Dickey (from an equivalent function written in 1988 for BSD curses).
