revtwoway - Reverse strings sample two-way processor extension

@load “revtwoway”

  BEGIN {
      cmd = "/magic/mirror"
      print "hello, world" |& cmd
      cmd |& getline result
      print result
      close(cmd)
  }

The revtwoway extension adds a simple two-way processor that reverses the characters in each line sent to it for reading back by the AWK program. It’s main purpose is to show how to write a two-way extension, although it may also be mildly amusing.
