自旋锁和信号灯之间的区别 [英] Differences between a spinlock and a semaphore

问题描述

自旋锁和信号量有什么区别?

What are the differences between a spinlock and a semaphore?

推荐答案

自旋锁使过程不断循环直到自旋锁被释放，而信号量则导致自旋锁进入睡眠直到释放的过程.

如果您要等待更长的时间才能满足条件，通常最好使用信号灯.

A spinlock causes the process to continuously loop until the spinlock is released, while a semaphore causes the process to sleep until it''s released.

A semaphore is usually better if you''re going to be waiting a longer time for the criteria to be met.
