Register an alternate input handler process for the distribution channel identified by DHandle. Once this function has been called, InputHandler is the only process allowed to call erlang:dist_ctrl_put_data(DHandle, Data) with the DHandle identifing this distribution channel. 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. A registered name is an alias for a process identifier (pid). Se hela listan på learnyousomeerlang.com Erlang was designed for massive concurrency. A process is created and terminated extremelly fast, that's why you can actually have thousands of them.

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. The monitor will not be effected, if the registered name is unregistered. 2017-06-09 Extended process registry for erlang. Pages 1–10. Previous Chapter Next Chapter.
A registered name is an alias for a process identifier (pid). Scope name is used to register process locally, and to name an ETS table. If there is another process registered under this name, or another ETS table exists, scope fails to start. Local membership is not preserved if scope process exits and restarts. Erlang was designed for massive concurrency. A process is created and terminated extremelly fast, that's why you can actually have thousands of them. A process executes some piece of code, then it terminates.

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. The monitor will not be effected, if the registered name is unregistered.
