I’m trying to figure out a way to initiate a call to the Elixir application from a linked port driver. I have a library in C, which functions as a server. It creates a thread when it’s initialised from Elixir, which sevices network requests in C. I can make calls from Elixir down to the driver and send messages to it. However, if the server needs to respond to a request, it cannot make calls back up to Elixir. I thought this would be straightfoward with driver_output() function, but then I don’t have the driver handle and I suppose the message in Elixir would be handled asynchronously too.
Any suggestions as to how this can be done?
