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

[Sergej Jurecko]

I just copy ErlNifPid to a C structure and use it from another thread. The environment used on that other thread was created with enif_alloc_env.

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?
