<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.
|
|
|
|
|

|
|
<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.
|
|
|
|
If the environment variables <STRONG>LINES</STRONG> or <STRONG>COLUMNS</STRONG> are set,
|
|
this overrides the library's use of the window size
|
|
obtained from the operating system. Thus, even if a SIG-
|
|
WINCH is received, no screen size change may be recorded.
