[erlang-questions] What is the proper way of sending messages to pid from enif thread?

[Max Lapshin]

Hi.


I've created thread in nif function.  When I create thread, I know pid of
caller:

  ErlNifPid self;
  enif_self(env, &self);


But later in thread I need to create some environment and send message to
this pid.

What is the proper way to save this ErlNifPid in C structure so that code
in other thread will be able to send messages.

And as far as I understand, I need to call  enif_alloc_env in that thread?
