-<H2>DESCRIPTION</H2><PRE>
- This is an extension to the curses library. It provides
- callers with a hook into the <STRONG>ncurses</STRONG> data to resize win-
- dows, primarily for use by programs running in an X Window
- terminal (e.g., xterm). The function <STRONG>resizeterm</STRONG> resizes
- the standard and current windows to the specified dimen-
- sions, and adjusts other bookkeeping data used by the
- <STRONG>ncurses</STRONG> library that record the window dimensions.
-
- Most of the work is done by the inner function
- <STRONG>resize_term</STRONG>. The outer function <STRONG>resizeterm</STRONG> adds bookkeep-
- ing for the SIGWINCH handler. When resizing the windows,
- <STRONG>resize_term</STRONG> blank-fills the areas that are extended. The
- calling application should fill in these areas with appro-
- priate data. The <STRONG>resize_term</STRONG> function attempts to resize
- all windows. However, due to the calling convention of
- pads, it is not possible to resize these without addi-
- tional interaction with the application.
-
- A support function <STRONG>is_term_resized</STRONG> is provided so that
- applications can check if the <STRONG>resize_term</STRONG> function would
- modify the window structures. It returns TRUE if the win-
- dows would be modified, and FALSE otherwise.
-
-
-</PRE>
-<H2>RETURN VALUE</H2><PRE>
- Except as notes, these function return the integer <STRONG>ERR</STRONG>
- upon failure and <STRONG>OK</STRONG> on success. They will fail if either
- of the dimensions are less than or equal to zero, or if an
- error occurs while (re)allocating memory for the windows.
-
-
-</PRE>
-<H2>NOTES</H2><PRE>
- While these functions are intended to be used to support a
- signal handler (i.e., for SIGWINCH), care should be taken
- to avoid invoking them in a context where <STRONG>malloc</STRONG> or <STRONG>real-</STRONG>
- <STRONG>loc</STRONG> may have been interrupted, since it uses those func-
- tions.
-
- If ncurses is configured to supply its own SIGWINCH han-
- dler, the <STRONG>resizeterm</STRONG> function ungetch's a <STRONG>KEY_RESIZE</STRONG> which
- will be read on the next call to <STRONG>getch</STRONG>. This is used to
- alert an application that the screen size has changed, and
- that it should repaint special features such as pads that
- cannot be done automatically.

- for BSD curses).
