My NIF is blocking and it is hard to make it non blocking, so I wrapped the entire function into a C thread, my NIF now spawn the thread and return immediately, then the thread sends the message. It seems to be a recommenced architecture in the documentation.
Threaded NIF - This is accomplished by dispatching the work to another thread managed by the NIF library, return from the NIF, and wait for the result. The thread can send the result back to the Erlang process using enif_send. Information about thread primitives is provided below.
Now my question is more about the user API which I want to make synchronous for API simplificy sake, so I thought of this task trick (which works fine). But I was wondering it was the right approach or if there was a more idiomatic way to do it.
In fact it is to make an async call synchronous in general, not really tied to a nif.
