+#| "I<abstract>: an abstract socket address is distinguished by the fact that "
+#| "I<sun_path[0]> is a null byte (\\(aq\\e0\\(aq). The socket's address in "
+#| "this namespace is given by the additional bytes in I<sun_path> that are "
+#| "covered by the specified length of the address structure. (Null bytes in "
+#| "the name have no special significance.) The name has no connection with "
+#| "file system pathnames. When the address of an abstract socket is "
+#| "returned by B<getsockname>(2), B<getpeername>(2), and B<accept>(2), the "
+#| "returned I<addrlen> is greater than I<sizeof(sa_family_t)> (i.e., greater "
+#| "than 2), and the name of the socket is contained in the first I<(addrlen "
+#| "- sizeof(sa_family_t))> bytes of I<sun_path>. The abstract socket "
+#| "namespace is a nonportable Linux extension."
