This is an extension to the curses library. It provides callers with a
- hook into the <STRONG>ncurses</STRONG> data to resize windows, primarily for use by pro-
- grams running in an X Window terminal (e.g., xterm).

Most of the work is done by the inner function <STRONG>resize_term</STRONG>. The outer
function <STRONG>resizeterm</STRONG> adds bookkeeping for the <STRONG>SIGWINCH</STRONG> handler, as well
- as repainting the soft-key area (see <STRONG><A HREF="slk_touch.3x.html">slk_touch(3x)</A></STRONG>).

When resizing the windows, <STRONG>resize_term</STRONG> blank-fills the areas that are
extended. The calling application should fill in these areas with

Except as noted, these functions return the integer <STRONG>ERR</STRONG> upon failure
and <STRONG>OK</STRONG> on success. They will fail if either of the dimensions are less

- ory for the windows.

- While these functions are intended to be used to support a signal han-

- in a context where <STRONG>malloc</STRONG> or <STRONG>realloc</STRONG> may have been interrupted, since
- it uses those functions.

resize the ncurses data structures.
