- The ::EslTcp4Listen 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 TCPv4 network layer calls
- ::EslTcp4ListenComplete to complete the connection processing.
- EslTcp4ListenComplete 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 ::EslTcp4Accept to remove the next connection from the queue
- and get the associated socket.
