**wresize** - resize a curses window

**#include** **<curses.h>**
**int** **wresize(WINDOW** ***win,** **int** **lines,** **int** **columns);**

This is an extension to the curses library. It reallo-
cates storage for an **ncurses** window to adjust its dimen-
sions 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 rendi-
tion (as set by **wbkgdset**) 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)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
**resizeterm**. The caller must ensure that the window's
dimensions fit within the actual screen dimensions.
