理解Unix Stream Socket

• Unix domain socket

  A Unix domain socket or IPC socket(inter-process communication socket) is a data communication endpoint for exchanging data between processes executing on the same host OS.

  Valid socket types in the UNIX domain are:

  • sock_stream : for a stream-oriented socket
  • sock_dgram : for a datagram-oriented socket
  • sock_seqpacket : for a sequenced-packet socket that is connection-oriented

• Communication endpoint

  A communication endpoint is a type of communication network node.
