  // = TITLE
  //     An abstract class which forms the basis for more specific
  //     classes (such as ACE_SOCK_Acceptor and ACE_SOCK_Connector).
  //     Do not instantiate this class.
  //  
  // = DESCRIPTION
  //    This class provides functions that are common to all of the
  //    SOCK-type classes. ACE_SOCK provides the ability to get and
  //    set socket options, get the local and remote addresses, and
  //    close the socket.

  ~ACE_SOCK (void);
  // Default ctor/dtor.

  // Wrapper around the setsockopt() system call.

                  void *optval,

  // Wrapper around the getsockopt() system call.

  int close (void);
  // Close down the socket.

  int get_local_addr (ACE_Addr &) const;
  // Return the local endpoint address in the referenced ACE_Addr.
  // Returns 0 if successful, else -1.

  int get_remote_addr (ACE_Addr &) const;
  // Return the address of the remotely connected peer (if there is
  // one), in the referenced ACE_Addr. Returns 0 if successful, else -1.

  void dump (void) const;
  // Dump the state of an object.

  // Declare the dynamic allocation hooks.
