基于Futex的锁定机制 [英] Futex based locking mechanism

问题描述

有人可以告诉我一个使用基于futex的锁定机制的例子？ （对于muticore x86 CPU，CentOS）

Somebody can tell me an example of using locking mechanism based on futex? (for muticore x86 CPU, CentOS)

推荐答案

Pthreads的互斥是在最新版本的Linux上使用futexes实现的。 Pthreads 是Linux上的标准C线程API，是的Posix标准，因此您可以轻松地将程序移植到其他类Unix系统。你应该避免直接使用futexes，除非你有非常不寻常的需求，因为他们很难正确使用 - 使用pthreads或更高级别的语言特定的API（几乎肯定会使用pthreads本身）。

Pthreads' mutexes are implemented using futexes on recent versions of Linux. Pthreads is the standard C threading API on Linux, and is part of the Posix standard, so you can easily port your program to other Unix-like systems. You should avoid using futexes directly unless you have very unusual needs, because they're very hard to use correctly - use pthreads, or a higher-level, language-specific API (which will almost certainly use pthreads itself).
