This section informs on interoperability, that is, information exchange, between Erlang and other programming languages. The included examples mainly treat interoperability between Erlang and C.
The purpose of this tutorial is to describe different interoperability mechanisms that can be used when integrating a program written in Erlang with a program written in another programming language, from the Erlang programmer's perspective.
It is assumed that you are a skilled Erlang programmer, familiar with concepts such as Erlang data types, processes, messages, and error handling.
To illustrate the interoperability principles, C programs running in a UNIX environment have been used. It is assumed that you have enough knowledge to apply these principles to the relevant programming languages and platforms.
For readability, the example code is kept as simple as possible. For example, it does not include error handling, which might be vital in a real-life system.
