[erlang-questions] gen_udp in passive mode

Running a UDP socket in passive mode, you retrieve the packets using
gen_udp:recv(Socket, Length). I could not find any reference to what
Length is used for in the documentation (Other than being used in
gen_tcp module when packet types are raw). Is there a reason to have it
here other than symmetry in the call among the modules?
I recall a thread on the mailing list some time ago, but might be wrong
as I could not find any reference to it.
