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 mildy amusing.
