You can spawn the same process while atomically linking it to the current one: spawn_link (my_module, function_name, [Arg]). When two processes are linked Value = string () Returns the process identifier of the current Erlang emulator in the format most commonly used by the OS environment. Returns Value as a string containing the (usually) numerical identifier for a process. On Unix, this is typically the return value of the getpid () system call.

Thing is, these are really very different in nature and these differences are not widely understood by beginners. 2011-05-26 · The communication model (among processes) in Erlang is message passing. No much need to be said about this. Erlang processes share no memory. The way that processes communicate is via (asynchronous) message passing.

12.2 Process Creation. A process is created by calling spawn: An alternative way to write the above without generating Anonymous Funs would be to spawn an erlang:apply/2 which can execute functions with given parameters. By passing a Function Ref. to erlang:apply/2, we can reference a local function and invoke it with the given arguments.
