We create a new concurrent process by calling the spawn
function. The spawn
function will get as parameter a function Fun
that the process will evaluate. The return value of the spawn
function is the created process identifier (pid).
1> Fun = fun() -> 2+2 end.
#Fun<erl_eval.20.52032458>
2> Pid = spawn(Fun).
<0.60.0>
You can also use spawn/3
to start a process that will execute a specific function from a module: spawn(Module, Function, Args)
.
Or use spawn/2
or spawn/4
similarly to start a process in a different node: spawn(Node, Fun)
or spawn(Node, Module, Function, Args)
.
