</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
The <STRONG>keybound</STRONG> <EM>ncurses</EM> extension permits a <EM>curses</EM> application to obtain
the value of the string <EM>bound</EM> to the function key <EM>key-code</EM>; see
<STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG> (wide-character API users: <STRONG><A HREF="curs_get_wch.3x.html">wget_wch(3x)</A></STRONG>). By default, such
bindings are string capabilities from the <EM>terminfo</EM> database entry
corresponding to the terminal type. The application can non-
destructively and repeatedly override such definitions with
<STRONG><A HREF="define_key.3x.html">define_key(3x)</A></STRONG>, as if by pushing new definitions onto a stack. The
<EM>count</EM> parameter accesses the <EM>n</EM>th most recently defined binding; <STRONG>0</STRONG>
selects the binding that is used on input.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
If <EM>key-code</EM> corresponds to a function key defined by the application or
the terminal type in use, <STRONG>keybound</STRONG> allocates and returns a string that
must be freed by the application. <STRONG>keybound</STRONG> returns <EM>NULL</EM> if <EM>key-code</EM> is
not positive or if it does not correspond to a key code definition.

<STRONG>keybound</STRONG> is an <EM>ncurses</EM> extension.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
Applications employing <EM>ncurses</EM> extensions should condition their use on
the visibility of the <STRONG>NCURSES_VERSION</STRONG> preprocessor macro.
