The Erlang process that creates a port is said to be the connected process of the port. All communication to and from the port must go through the connected process. If the connected process terminates, the port also terminates (and the Erlang is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system. The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform, which consists of the Erlang runtime system, several ready-to-use components mainly written in Erlang, and a set of design principles for Erlang programs.

Eftersom språket är designat för parallell bearbetning på flera sammankopplade system är det också synnerligen väl lämpat för användning på moderna flerkärniga Erlang has some pre-built attributes which can be attached to modules. Let’s take a look at them.

In Erlang, two functions of with the same name but with different arity are two different functions, and as such are each exported explicitly. To quote the Erlang documentation is says: A function is uniquely defined by the module name, function name, and arity. For example, if you have two functions: do_something() -> does_something().

print_all() ->. receive.

Many dynamically typed BEAM languages support Erlang’s typespecs, type annotations that can be analysed with the Dialyzer tool. Jan 17, 2015 -export(Functions). Exported functions is used to define which functions the module exports, where “exports” means that they will be available to May 18, 2018 Let's see how things work. Let's start by defining a module named test .

Type Specifications and Erlang PLTs Are The Best Sandwiches. Back in Types (or lack thereof), I introduced Dialyzer, a tool to find type errors in Erlang.This chapter puts its full focus on Dialyzer and how to actually find some type errors with Erlang, and how to use the tool to find other types of discrepancies. r/erlang: /r/Erlang is focused around the erlang programming language and its BEAM runtime. Other BEAM runtime languages are also welcome. 얼랭(Erlang, 영어: IPA: [ˈɜrlæŋ])은 범용 병렬 프로그래밍 언어이다.
