The built-in process registry has proven to be an extremely useful feature of the Erlang language. It makes it easy to provide named services, which can be reached without knowing the process iden- To give a process a name, the function erlang:register/2 is used. If the process dies, it will automatically lose its name or you can also use unregister/1 to do it manually. You can get a list of all registered processes with registered/0 or a more detailed one with the shell command regs() . Gproc is a process dictionary for Erlang, which provides a number of useful features beyond what the built-in dictionary has: Use any term as a process alias Register a process under several aliases Non-unique properties can be registered simultaneously by many processes erlang documentation: Creating Processes.
The alias will be globally available! It is very easy to create shared state, wich is usually not preferable.

Process Registries are an important concept in Elixir / Erlang. Don't let that confuse you with how Process.register/2 is used — while Process.register/2

Sedan kan jag starta en handledare för att övervaka denna process: Elixir levereras också med ett lokalt, decentraliserat och skalbart register som heter som onda, särskilt i en mycket samtidigt miljö (det är därför du väljer Erlang / Elixir). Det är lämpligt att använda tecken i olika register.

To give a process a name, use erlang:register(Name,Pid). If the process dies, it will loose its name. Or you can use unregister/1 to do it manually. Then, use whereis(Name) to get Pid (or an undefined). When a process is monitored by registered name, the process that has the registered name at the time when erlang:monitor/2 is called will be monitored.
Prior to 2009, Erlang libraries were not well organized, making it difficult to install libraries from other programmers. The first version of rebar helped to improve the management process. Erlang - register - This is used to register a process in the system. Erlang register process.

However, the current registry also has limitations: names can only be atoms (unstructured), processes can register under at most one name, and it offers no means of efficient search and iteration. 2019-11-18 The ability to globally register names is a central concept in the programming of distributed Erlang systems. In this module, the equivalent of the register/2 and whereis/1 BIFs (for local name registration) are provided, but for a network of Erlang nodes.

3 Aug 2019 We can register a process on its host node by invoking the register(RegName, PidOrPort) function, where RegName is an arbitrary name
The downside of this is that we can no longer call arbitrary C code as it may assume a much larger stack, requiring us to swap back and forth between a “C stack” and the “Erlang … newly started Erlang node already contains 13 registered processes. However, the built-in process registry imposes several, some-times unwelcome, limitations: registered names are restricted to be atoms, the same process cannot be registered with multiple names, and there is no efficient way to search the registry (other than by name lookup). 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. 2016-11-02 Erlang - Exceptions In comparison with exits and errors, they don't really carry any 'crash that process!' intent behind them, but rather they control the flow.
