Class Description

                                                                      
 TPSocket                                                             
                                                                      
 This class implements parallel client sockets. A parallel socket is  
 an endpoint for communication between two machines. It is parallel   
 because several TSockets are open at the same time to the same       
 destination. This especially speeds up communication over Big Fat    
 Pipes (i.e. high bandwidth, high latency WAN connections).           
                                                                      

 Create a parallel socket. Connect to the named service at address addr.
 Use tcpwindowsize to specify the size of the receive buffer, it has
 to be specified here to make sure the window scale option is set (for
 tcpwindowsize > 65KB and for platforms supporting window scaling).
 Returns when connection has been accepted by remote side. Use IsValid()
 to check the validity of the socket. Every socket is added to the TROOT
 sockets list which will make sure that any open sockets are properly
 closed on program termination.

 Create a parallel socket. Connect to the specified port # at address addr.
 Use tcpwindowsize to specify the size of the receive buffer, it has
 to be specified here to make sure the window scale option is set (for
 tcpwindowsize > 65KB and for platforms supporting window scaling).
 Returns when connection has been accepted by remote side. Use IsValid()
 to check the validity of the socket. Every socket is added to the TROOT
 sockets list which will make sure that any open sockets are properly
 closed on program termination.

 Create a parallel socket. Connect to named service on the remote host.
 Use tcpwindowsize to specify the size of the receive buffer, it has
 to be specified here to make sure the window scale option is set (for
 tcpwindowsize > 65KB and for platforms supporting window scaling).
 Returns when connection has been accepted by remote side. Use IsValid()
 to check the validity of the socket. Every socket is added to the TROOT
 sockets list which will make sure that any open sockets are properly
 closed on program termination.

 Create a parallel socket. Connect to specified port # on the remote host.
 Use tcpwindowsize to specify the size of the receive buffer, it has
 to be specified here to make sure the window scale option is set (for
 tcpwindowsize > 65KB and for platforms supporting window scaling).
 Returns when connection has been accepted by remote side. Use IsValid()
 to check the validity of the socket. Every socket is added to the TROOT
 sockets list which will make sure that any open sockets are properly
 closed on program termination.

 Create a parallel socket on a connection already opened via
 TSocket sock.
 This constructor is provided to optimize TNetFile opening when
 instatiated via a call to TXNetFile.
 Returns when connection has been accepted by remote side. Use IsValid()
 to check the validity of the socket. Every socket is added to the TROOT
 sockets list which will make sure that any open sockets are properly
 closed on program termination.

 Create a parallel socket. This ctor is called by TPServerSocket.

 Cleanup the parallel socket.

 Close a parallel socket. If option is "force", calls shutdown(id,2) to
 shut down the connection. This will close the connection also
 for the parent of this process. Also called via the dtor (without
 option "force", call explicitely Close("force") if this is desired).

 Create a parallel socket to the specified host.

 Return internet address of local host to which the socket is bound.
 In case of error TInetAddress::IsValid() returns kFALSE.

 Return socket descriptor

 Send a TMessage object. Returns the number of bytes in the TMessage
 that were sent and -1 in case of error. In case the TMessage::What
 has been or'ed with kMESS_ACK, the call will only return after having
 received an acknowledgement, making the sending process synchronous.
 Returns -4 in case of kNoBlock and errno == EWOULDBLOCK.

 Send a raw buffer of specified length. Returns the number of bytes
 send and -1 in case of error.

 Receive a TMessage object. The user must delete the TMessage object.
 Returns length of message in bytes (can be 0 if other side of connection
 is closed) or -1 in case of error or -4 in case a non-blocking socket would
 block (i.e. there is nothing to be read). In those case mess == 0.

 Send a raw buffer of specified length. Returns the number of bytes
 sent or -1 in case of error.

 Set socket options.

 Get socket options. Returns -1 in case of error.

 Returns error code. Meaning depends on context where it is called.
 If no error condition returns 0 else a value < 0.
