+=head1 DESCRIPTION
+
+The B<BIO_ADDRINFO> type is a wrapper for address information
+types provided on your platform.
+
+B<BIO_ADDRINFO> normally forms a chain of several that can be
+picked at one by one.
+
+BIO_lookup() looks up a specified B<host> and B<service>, and
+uses B<lookup_type> to determine what the default address should
+be if B<host> is B<NULL>.  B<family>, B<socktype> are used to
+determine what protocol family and protocol should be used for
+the lookup.  B<family> can be any of AF_INET, AF_INET6, AF_UNIX and
+AF_UNSPEC, and B<socktype> can be SOCK_STREAM or SOCK_DGRAM.
+B<res> points at a pointer to hold the start of a B<BIO_ADDRINFO>
+chain.
+For the family B<AF_UNIX>, BIO_lookup() will ignore the B<service>
+parameter and expects the B<node> parameter to hold the path to the
+socket file.
+
+BIO_ADDRINFO_family() returns the family of the given
+B<BIO_ADDRINFO>.  The result will be one of the constants
+AF_INET, AF_INET6 and AF_UNIX.
+
+BIO_ADDRINFO_socktype() returns the socket type of the given
+B<BIO_ADDRINFO>.  The result will be one of the constants
+SOCK_STREAM and SOCK_DGRAM.
+
+BIO_ADDRINFO_protocol() returns the protocol id of the given
+B<BIO_ADDRINFO>.  The result will be one of the constants
+IPPROTO_TCP and IPPROTO_UDP.
+
+BIO_ADDRINFO_address() returns the underlying B<BIO_ADDR>
+of the given B<BIO_ADDRINFO>.
+
+BIO_ADDRINFO_next() returns the next B<BIO_ADDRINFO> in the chain
+from the given one.
+
+BIO_ADDRINFO_free() frees the chain of B<BIO_ADDRINFO> starting
+with the given one.
+
+=head1 RETURN VALUES
+
+BIO_lookup() returns 1 on success and 0 when an error occurred, and
+will leave an error indication on the OpenSSL error stack in that case.
+
+All other functions described here return 0 or B<NULL> when the
+information they should return isn't available.
