If you want to return the message to the same process that called the driver
(not necessarily the port owner) you can retrieve this using:

ErlDriverTerm driver_caller(ErlDrvPort port)

It's documented in the erts Ref manual in the erl_drver section.

If you want to send it to some other arbritrary process I'm not sure there's
a standard way.
