cp in erlang traces

[Joel Reymont]

Assume a trace from erlang:trace that looks like this:

{trace_ts, Pid, call, {_M, _F, Arity} = Func, {cp, CP}, TS}

What does CP stand for here and how would you use it if you were building your own profiler?

This does not seem to be documented in the man page for erlang:trace.

	Thanks, Joel
