8 interface over TCP for generic application protocols. With KCM an application
9 can efficiently send and receive application protocol messages over TCP using

46 written on a KCM socket are sent atomically on an appropriate TCP socket.
47 Similarly, in the receive path, messages are constructed on each TCP socket
50 TCP sockets & Psocks
53 TCP sockets may be bound to a KCM multiplexor. A Psock structure is allocated
54 for each bound TCP socket, this structure holds the state for constructing
60 Each multiplexor assumes that all attached TCP connections are to the same
73 Messages are sent over a TCP stream with some application protocol message
78 A TCP stream must be parsed to determine message boundaries. Berkeley Packet
79 Filter (BPF) is used for this. When attaching a TCP socket to a multiplexor a

89 When a TCP socket is attached to a KCM multiplexor data ready (POLLIN) and

92 posted on the TCP socket so that a POLLERR event happens and KCM discontinues
