Hi guys,

I need to convert erlang_pid structure into ErlDrvTermData that will be passed to
driver_send_term(ErlDrvPort ix, ErlDrvTermData to, ErlDrvTermData* data, int len) function in linked-in driver.

Is it possible to achieve?

Best Regards,
Sergey

Hi Sergey,
I think what you are looking for is
http://www.erlang.org/doc/man/erl_driver.html#driver_caller
"This function returns the process id of the process that made the current
call to the driver. The process id can be used withdriver_send_term to send
back data to the caller".
or

Hello Ahmed,

Thanks a lot!
What I'd like to achieve is to send messages to any erlang process from a separate thread in a driver.
The only thing I was able to find is the following blog entry http://dudefrommangalore.blogspot.com/2009/03/rpc-from-erlang-linked-in-driver-port.html. According to the latest sources of the otp, this way should still be valid.

Regards,
Sergey
