spawn_link((() -> any())) :: pid()

Spawns the given function, links it to the current process, and returns its PID.

Typically developers do not use the spawn functions, instead they use abstractions such as Task, GenServer and Agent, built on top of spawn, that spawns processes with more conveniences in terms of introspection and debugging.

Check the Process module for more process-related functions. For more information on linking, check Process.link/1.

The anonymous function receives 0 arguments, and may return any value.

Inlined by the compiler.

Examples

current = self()
child = spawn_link(fn -> send(current, {self(), 1 + 2}) end)

receive do
  {^child, 3} -> IO.puts("Received 3 back")
end
