\section ConnectionManagement Connection Management
The ::EslTcp6Listen routine initially places the SOCK_STREAM or
SOCK_SEQPACKET socket into a listen state. When a remote machine
makes a connection to the socket, the TCPv6 network layer calls
::EslTcp6ListenComplete to complete the connection processing.
EslTcp6ListenComplete manages the connections by placing them in
FIFO order in a queue to be serviced by the application. When the
number of connections exceeds the backlog (ESL_SOCKET::MaxFifoDepth),
the new connection is closed. Eventually, the application indirectly
calls ::EslTcp6Accept to remove the next connection from the queue
and get the associated socket.

Attempt to connect to a remote TCP port
This routine starts the connection processing for a SOCK_STREAM
or SOCK_SEQPAKCET socket using the TCPv6 network layer. It
configures the local TCPv6 connection point and then attempts to
connect to a remote system. Upon completion, the
::EslTcp6ConnectComplete routine gets called with the connection
status.
This routine is called by ::EslSocketConnect to initiate the TCPv6
network specific connect operations. The connection processing is
initiated by this routine and finished by ::EslTcp6ConnectComplete.

connection points until a connection to the remote system is
made.

Buffer data for transmission over a network connection.
This routine buffers data for the transmit engine in one of two
queues, one for urgent (out-of-band) data and the other for normal
data. The urgent data is provided to TCP as soon as it is available,
allowing the TCP layer to schedule transmission of the urgent data
between packets of normal data.
This routine is called by ::EslSocketTransmit to buffer
data for transmission. When the \ref TransmitEngine has resources,
this routine will start the transmission of the next buffer on
the network connection.
Transmission errors are returned during the next transmission or
during the close operation. Only buffering errors are returned
during the current transmission attempt.
