.SH "Detailed Description"
.PP 
TCPV6 sockets are used for stream based connected sessions between two ipv6 sockets\&. 

Both error recovery and flow control operate transparently for a TCP socket connection\&. The TCP socket base class is primary used to bind a TCP 'server' for accepting TCP streams\&.
.PP
An implicit and unique \fBTCPV6Socket\fP object exists in Common C++ to represent a bound ipv6 TCP socket acting as a 'server' for receiving connection requests\&. This class is not part of \fBTCPStream\fP because such objects normally perform no physical I/O (read or write operations) other than to specify a listen backlog queue and perform 'accept' operations for pending connections\&. The Common C++ \fBTCPV6Socket\fP offers a Peek method to examine where the next pending connection is coming from, and a Reject method to flush the next request from the queue without having to create a session\&.
.PP
The \fBTCPV6Socket\fP also supports a 'OnAccept' method which can be called when a \fBTCPStream\fP related object is created from a \fBTCPSocket\fP\&. By creating a \fBTCPStream\fP from a \fBTCPV6Socket\fP, an accept operation automatically occurs, and the \fBTCPV6Socket\fP can then still reject the client connection through the return status of it's OnAccept method\&.

.PP
A TCP 'server' is created as a TCP socket that is bound to a hardware address and port number on the local machine and that has a backlog queue to listen for remote connection requests\&. If the server cannot be created, an exception is thrown\&.

Create a TCP server for a named host interface and service port\&. We use [host/]port for specifying the optional host name and service port since ':' is a valid char for ipv6 addresses\&.

.PP
A method to call in a derived \fBTCPSocket\fP class that is acting as a server when a connection request is being accepted\&. The server can implement protocol specific rules to exclude the remote socket from being accepted by returning false\&. The Peek method can also be used for this purpose\&.
