Erlang::Terms. Includes simple immutable classes that represent Erlang's atom, binary, bitstring, compressed, export, function, list, map, nil, pid, port, reference

Erlang provides a number of data types which are listed in this chapter. A piece of data of any data type is called a term. 3.2 Number. There are two types of numeric literals, integers and floats. Besides the conventional notation, there are two Erlang-specific notations: $ char ASCII value of …

I got a question from Ivo Danihelka about make_ref(). Isn't make_ref() supposed to generate "an almost unique reference" the manual says "Returns an almost unique Running Erlang zThe Erlang VM emulator is called 'erl' zThe interactive shell lets you write any Erlang expressions and run them (must end with '.') zThe “1>”, “2>”, etc. is the shell input prompt zThe “halt()” function call exits the emulator $ erl Erlang (BEAM) emulator version 5.10.3 Eshell V5.10.3 (abort with ^G) 1> 6*7. 42 2 The Erlang BEAM system allows mixing threaded code emulation with compiling into C.

Η Erlang είναι γλώσσα προγραμματισμού γενικών καθηκόντων με χαρακτηριστικά ταυτοχρονισμού (concurrency) και συλλογής απορριμμάτων.Το ίδιο όνομα αναφέρεται και στο σύστημα χρόνου εκτέλεσής της (runtime system).

Technique for running Erlang NIFs functions asynchronously, not on scheduler threads. - async_nif.h Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) 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 (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs.

How do we implement a reset countdown timer with GenServer? 1) complete the task after a certain amount of time, say, every 60 seconds. 2) have a way to reset the countdown to 60 seconds before the timer expires.

Error management with multiple processes in Erlang: links, monitors, exit signals (and how to trap them), the logic behind being able to give Instead, we'll use references (created with make_ref() ) as unique values to identify me

Unique for calls up to 2 ^ 82, which should be sufficient for your purposes. I find this easier than formatting a timestamp named node to use. 2017-04-28 Next message (by thread): [erlang-questions] make_ref bug or feature? Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] I was putting Refs into a term and then serializing them with term_to_binary and sending them into a socket to another independent Erlang system (ie not using distributed Erlang) - so yes it was a problem since I'd assumed these were unique.
