 * @class ACE_SOCK

 * @brief An abstract class that forms the basis for more specific
 * classes, such as ACE_SOCK_Acceptor and ACE_SOCK_Stream.
 * Do not instantiate this class.
 *
 * This class provides functions that are common to all of the
 * <ACE_SOCK_*> classes. ACE_SOCK provides the ability to get
 * and set socket options, get the local and remote addresses,
 * and open and close a socket handle.
