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.
