**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 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 **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.

**resizeterm**(3X).
