<span style=" font-family:'Courier New'; font-size: 9pt;">Hello Ahmed,<br>
<br>
Thanks a lot!<br>
What I'd like to achieve is to send messages to any erlang process from a separate thread in a driver.<br>
The only thing I was able to find is the following blog entry </span><a style=" font-family:'Courier New'; font-size: 9pt;" href="http://dudefrommangalore.blogspot.com/2009/03/rpc-from-erlang-linked-in-driver-port.html">http://dudefrommangalore.blogspot.com/2009/03/rpc-from-erlang-linked-in-driver-port.html.</a><span style=" font-family:'Courier New'; font-size: 9pt;"> According to the latest sources of the otp, this way should still be valid.<br>
<br>
Regards,<br>
Sergey<br>

Hi guys,<br>
<br>
I need to convert erlang_pid structure into ErlDrvTermData that will be passed to <br>
driver_send_term(ErlDrvPort ix, ErlDrvTermData to, ErlDrvTermData* data, int len) function in linked-in driver.<br>
<br>
Is it possible to achieve? <br>
<br>
Best Regards,<br>
Sergey<br>
