revtwoway(3) Reverse strings sample two-way processor extension


@load "revtwoway"

cmd = "/magic/mirror"
print "hello, world" |& cmd
cmd |& getline result
print result


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. # .SH BUGS
