I'm getting started with Erlang, and could use a little help understanding the different results when applying the PID returned from spawn/3 to the process_info/1 method. Given this simple code where the a/0 function is exported, which simply invokes b/0, which waits for a message:-module(tester). -export([a/0]).
另外，spawn函數另外有程序連接版本，spawn_link函數，同時啟動並連接到新程序。 分散式程式設計 . Erlang提供分散式機制，能在另一台電腦啟動一些Erlang程序，並由本機電腦對其他電腦的Erlang程序傳遞訊息。
On Unix, this is typically the return value of the getpid () system call.

2021-04-17 · Erlang is designed for massive concurrency. Erlang processes are lightweight (grow and shrink dynamically) with small memory footprint, fast to create and terminate, and the scheduling overhead is low. 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. The following implements this solution: and there are distribution data available, a call to erlang:dist_ctrl_get_data(DHandle) will return Data to pass over the channel as well as the Size of Data in bytes. This is returned as a tuple on the form {Size, Data}.
Erlang processes are light-weight (grow and shrink dynamically) with small memory footprint, fast to create and terminate and the scheduling overhead is low. 12.2 Process Creation. A process is created by calling spawn: Thus erlang:hibernate/3 will never return to its caller.

Lumen - Statically compiled Erlang for x86 2021-04-08. The Lumen Project is an ambitious compiler development effort to create a complimentary set of compilers and tools that allow developers to get the power of the Erlang VM, The BEAM, in places it does not traditionally fit. The error handler can be redefined (see process_flag/2 ). If error_handler is undefined, or the user has redefined the default error_handler its replacement is undefined, a failure with the reason undef will occur. > spawn (speed, regulator, [high_speed, thin_cut]).
