Question

Can someone explain the structure of a Pid in Erlang?

Pids looks like this : , e.g. <0.30.0> , but i would like to kno

Answer 1

If I remember this correctly the format is . 0 is current node much like a computer always has the hostname "localhost" to refer to itself. This is by old memory so it might not be 100% correct tough.

But yes. You could build the pid with list_to_pid/1 for example.

PidString = "<0.39.0>",
list_to_pid(PidString) ! message.

Of course. You just use whatever method you need to use to build your PidString. Probably write a function that generates it and use that instead of PidString like such:

list_to_pid( make_pid_from_term({proc_name, Node}) ) ! message
