Try is_pid(Pid) ;-)
How does From get set?
The "right" way is to receive it from the client (who sends a Pid) and
then it can be used as From ! Message regardless of whether it's local
or remote. This means the C node has to send it's pid to a registered
process on the Erlang node first.
Of course, if the Erlang side has to initiate the conversation,
there's little choice. Something like the following might make it more
portable
-ifdef(LOCAL_TEST).
-define(DEST, local_process_name).
-else.
-define(DEST, {any, cnode@REDACTED}).
-endif.
.....
?DEST! GatewayPid.
best regards,
Vlad
