Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

|

These <EM>ncurses</EM> extensions to the <EM>curses</EM> library do not fit easily into
|
|
other functional categories.

|
|
|
|
|
</PRE><H3><a name="h3-curses_version">curses_version</a></H3><PRE>
|
|
<STRONG>curses_version</STRONG> returns a pointer to a string containing the library's
|
|
name and version number, including its patch level, for example
|
|
"ncurses 6.5.20240720".
|
|
|
|
|
|
</PRE><H3><a name="h3-use_extended_names">use_extended_names</a></H3><PRE>
|
|
<STRONG>use_extended_names</STRONG> configures whether the library recognizes user-
|
|
defined or nonstandard <EM>terminfo</EM> capability names that may be compiled
|
|
into terminal type descriptions via the <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(3x)</A></STRONG> or
|
|
<STRONG><A HREF="curs_termcap.3x.html">curs_termcap(3x)</A></STRONG> interfaces. Normally these names are available for
|
|
use, since the essential decision is made through use of <STRONG><A HREF="tic.1m.html">tic(1)</A></STRONG>'s <STRONG>-x</STRONG>
|
|
option to include such extensions in terminal type descriptions.
|
|
<STRONG>use_extended_names(FALSE)</STRONG> prevents <EM>ncurses</EM> from recognizing these
|
|
capabilities to ensure compatibility with other implementations of
|
|
<EM>curses</EM>.
|
|
|
|
|
|
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
|
|
<STRONG>curses_version</STRONG> returns a constant string.
|
|
|
|
<STRONG>use_extended_names</STRONG> returns the previous state of extended capability
|
|
name recognition, allowing you to save this property and restore it.
|
|
|
|
|
|
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
|
|
The pointer returned by <STRONG>curses_version</STRONG> corresponds to statically
|
|
allocated memory; do not attempt to <STRONG>free(3)</STRONG> it.

</PRE><H2><a name="h2-EXTENSIONS">EXTENSIONS</a></H2><PRE>

These functions are <EM>ncurses</EM> extensions, and are not found in SVr4
|
|
<EM>curses</EM>, 4.4BSD <EM>curses</EM>, or any other previous <EM>curses</EM> implementation.

|
|
Applications employing <EM>ncurses</EM> extensions should condition their use on
|
|
the visibility of the <STRONG>NCURSES_VERSION</STRONG> preprocessor macro.
|
|
|
|
NetBSD 9 added a <EM>curses</EM><STRONG>_</STRONG><EM>version</EM> function that intentionally returns a
|
|
string devoid of version information.
