 `/inet/tcp'

    Once again, always use TCP.  (Use UDP when low overhead is a
 necessity, and use RAW for network experimentation.)  The first example
 is the sender program:
 
      # Server
      BEGIN {
        print strftime() |& "/inet/tcp/8888/0/0"
        close("/inet/tcp/8888/0/0")
      }
 
    The receiver is very simple:
 
      # Client
      BEGIN {
        "/inet/tcp/0/localhost/8888" |& getline
        print $0
        close("/inet/tcp/0/localhost/8888")
      }
 
    TCP guarantees that the bytes arrive at the receiving end in exactly
 the same order that they were sent. No byte is lost (except for broken
 connections), doubled, or out of order. Some overhead is necessary to
 accomplish this, but this is the price to pay for a reliable service.
 It does matter which side starts first. The sender/server has to be
 started first, and it waits for the receiver to read a line.
