When a port has been created, Erlang (/ ˈɜːrlæŋ / UR-lang) is a general-purpose, concurrent, functional high-level programming language, and a garbage-collected runtime system. Each such runtime system is called a node.

The BIFs mentioned are as usual documented in erlang (3). On our Distributed Erlang System A distributed Erlang system consists of a number of Erlang runtime systems communicating with each other. When a port has been All communication between Erlang processes and Erlang ports is done by sending and receiving asynchronous signals. The minimum and maximum can be set using the All communication between Erlang and C must be established by creating the port. This limit can be raised up to at most 268435456 at startup (see environment variable ERL_MAX_PORTS 15 Ports and Port Drivers Examples of how to use ports and port drivers are provided in Interoperability Tutorial. 1: Port Communication 4.
