<div dir="ltr">Hello,<div><br></div><div>The only way that I know if from either driver_caller or driver_connected. What I have done to solve this problem is to make the process that should get the message "register" with the port. When it does the register call I get the pid using driver_caller and save the pid in the port state.</div>
<div><br></div><div>You should probably also monitor the process from the driver to in case it terminates.</div><div><br></div><div>Lukas</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Mon, Jun 23, 2014 at 2:02 PM, <a href="mailto:streamingmind@gmail.com">streamingmind@gmail.com</a> <span dir="ltr"><<a href="mailto:streamingmind@gmail.com" target="_blank">streamingmind@gmail.com</a>></span> wrote:<br>

<div><div><p style="margin-top:0;margin-bottom:0"> </p><p style="margin-top:0;margin-bottom:0">I've been practicing writing a port driver for a legacy SIGTRN product. In attempting to send back data from the port driver to a erlang process, I don't know how to convert existing erlang_pid data to a ErlDrvTerm data which is required by erl_drv_send_term(), as the receiver parameter. It'll be graceful if somebody here could give me a hand.</p>
