保证信号量顺序? [英] Guaranteed semaphore order?

问题描述

.NET Semaphore类的文档指出:

The documentation for the .NET Semaphore class states that:

没有保证的顺序(例如FIFO或LIFO)，阻止的线程在该顺序中进入信号量.

There is no guaranteed order, such as FIFO or LIFO, in which blocked threads enter the semaphore.

在这种情况下，如果我要保证订单(FIFO或LIFO)，我有什么选择?这是不容易做到的吗?我需要编写自己的信号量吗?我认为那会相当先进吗?

In this case, if I want a guaranteed order (either FIFO or LIFO), what are my options? Is this something that just isn't easily possible? Would I have to write my own Semaphore? I assume that would be pretty advanced?

谢谢

FifoSemaphore的工作原理与普通的Semaphore完全相同，但是还可以保证令牌以获取者设法获取内部锁的顺序提供给获取者. FifoSemaphore的用法与Semaphore相同.

The FifoSemaphore works exactly like a normal Semaphore but also guarantees that tokens are served out to acquirers in the order that they manage to acquire the internal lock. The usage of a FifoSemaphore is identical to a Semaphore.
