The macro ends up defined in terms of do-nothing inets:report_event/4
function -- its only purpose is to serve as target for native tracing
facility built into BEAM (and exposed to user via dbg(3) module).

There seem to be a couple of convenience functions that should make
the whole process much more user-friendly than raw dbg(3) API:

-export([enable_trace/2, enable_trace/3, disable_trace/0, set_trace/1,
report_event/4]).

Hopefully this should get you started -- I'm not using httpc(3) at all
and won't pretend to be very fluent with dbg(3) either.
