Distributed Erlang nodes provide a high-level model for integrating other languages with Erlang programs. With tinch++, your C++ code will be able to communicate with Erlang processes by means of message passing. To the Erlang processes, your C++ node will look and behave like any Erlang node.

A gen_server is a specific finite state machine working like a server. gen_server can handle different type of event: synchronous request with handle_call. asynchronous request with handle_cast. other message (not defined in OTP specification) with handle_info. Synchronous and asynchronous message are specified in OTP and are simple tagged tuples Se hela listan på 20bits.com The first OTP behaviour we'll see is one of the most used ones. Its name is gen_server and it has an interface a bit similar to the one we've written with my_server in last chapter; it gives you a few functions to use it and in exchange, your module has to already have a few functions gen_server will use.
