class TPServerSocket: public TServerSocket

 Create a parallel server socket object on a specified port. Set reuse
 to true to force reuse of the server socket (i.e. do not wait for the
 time out to pass). Using backlog one can set the desirable queue length
 for pending connections.
 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).
 Use IsValid() to check the validity of the
 server socket. In case server socket is not valid use GetErrorCode()
 to obtain the specific error value. These values are:
  0 = no error (socket is valid)
 -1 = low level socket() call failed
 -2 = low level bind() call failed
 -3 = low level listen() call failed
 Every valid server 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 server socket object for a named service. Set reuse

 Accept a connection on a parallel server socket. Returns a full-duplex
 parallel communication TPSocket object. If no pending connections are
 present on the queue and nonblocking mode has not been enabled
 with SetOption(kNoBlock,1) the call blocks until a connection is
 present. The returned socket must be deleted by the user. The socket
 is also added to the TROOT sockets list which will make sure that
 any open sockets are properly closed on program termination.
 In case of error 0 is returned and in case non-blocking I/O is
 enabled and no connections are available -1 is returned.
