ERLANG wait（）和阻塞 [英] ERLANG wait() and blocking

问题描述

一个很好的答案将详细介绍erlang和/或cpu的内部工作。

  wait（Sec） - > 
在（1000 * Sec）之后收到
  - > ok 
结束。 
  

解决方案

执行该代码块，运行该进程的调度程序当前将不会阻止。您发布的代码等于产量，但是超时。

该核心的Erlang VM调度程序将继续执行其他进程，直到超时触发并且该进程将被安排再次执行。

Does the following function block on its running core?

A great answer will detail the internal working of erlang and/or the cpu.

wait(Sec) -> 
    receive
    after (1000 * Sec) -> ok
    end.

解决方案

The process which executes that code will block, the scheduler which runs that process currently will not block. The code you posted is equal to a yield, but with a timeout.

The Erlang VM scheduler for that core will continue to execute other processes until that timeout fires and that process will be scheduled for execution again.
