+<H2>DESCRIPTION</H2>
+
+These functions fill in, and test for, special values of the
+<I>ip_address</I>
+
+type.
+<P>
+
+<I>Anyaddr</I>
+
+fills in the destination
+<I>*dst</I>
+
+with the ``any'' address of address family
+<I>af</I>
+
+(normally
+<B>AF_INET</B>
+
+or
+<B>AF_INET6</B>).
+
+The IPv4 ``any'' address is the one embodied in the old
+<B>INADDR_ANY</B>
+
+macro.
+<P>
+
+<I>Isanyaddr</I>
+
+returns
+<B>1</B>
+
+if the
+<I>src</I>
+
+address equals the ``any'' address,
+and
+<B>0</B>
+
+otherwise.
+<P>
+
+Similarly,
+<I>unspecaddr</I>
+
+supplies, and
+<I>isunspecaddr</I>
+
+tests for,
+the ``unspecified'' address,
+which may be the same as the ``any'' address.
+<P>
+
+Similarly,
+<I>loopbackaddr</I>
+
+supplies, and
+<I>islookbackaddr</I>
+
+tests for,
+the loopback address.
+<P>
+
+<I>Anyaddr</I>,
+
+<I>unspecaddr</I>,
+
+and
+<I>loopbackaddr</I>
+
+return
+<B>NULL</B>
+
+for success and
+a pointer to a string-literal error message for failure;
+see DIAGNOSTICS.
