NAME

       ost::TCPSession - The TCP session is used to primarily to represent a client connection that can be
       managed on a separate thread.

Detailed Description

       The TCP session is used to primarily to represent a client connection that can be managed on a separate
       thread.

       The TCP session also supports a non-blocking connection scheme which prevents blocking during the
       constructor and moving the process of completing a connection into the thread that executes for the
       session.

Constructor & Destructor Documentation

   ost::TCPSession::TCPSession (const IPV4Host & host, tpport_t port, size_t size = 536, int pri = 0, size_t
       stack = 0)
       Create a TCP socket that will be connected to a remote TCP server and that will execute under it's own
       thread.

       Parameters:
           host internet address of remote TCP server.
           port number of remote server.
           size of streaming buffer.
           pri execution priority relative to parent.
           stack allocation needed on some platforms.

   ost::TCPSession::TCPSession (const IPV6Host & host, tpport_t port, size_t size = 536, int pri = 0, size_t
       stack = 0)
   ost::TCPSession::TCPSession (TCPSocket & server, int pri = 0, size_t stack = 0)
       Create a TCP socket from a bound TCP server by accepting a pending connection from that server and
       execute a thread for the accepted connection.

       Parameters:
           server tcp socket to accept a connection from.
           pri execution priority relative to parent.
           stack allocation needed on some platforms.

Member Function Documentation

   void ost::TCPSession::initial (void) [protected],  [virtual]
       The initial method is used to esablish a connection when delayed completion is used. This assures the
       constructor terminates without having to wait for a connection request to complete.

       Reimplemented from ost::Thread.

   int ost::TCPSession::waitConnection (timeout_t timeout = TIMEOUT_INF) [protected]
       Normally called during the thread Initial() method by default, this will wait for the socket connection
       to complete when connecting to a remote socket. One might wish to use setCompletion() to change the
       socket back to blocking I/O calls after the connection completes. To implement the session one must
       create a derived class which implements run().

       Returns:
           0 if successful, -1 if timed out.

       Parameters:
           timeout to wait for completion in milliseconds.
