读者/作者锁定在C ++ [英] Reader/Writer Locks in C++

问题描述

我在C ++中寻找一个好的读写器锁。我们有一个单一的不常见的作家和许多频繁读者的用例，并希望优化这一点。首选我想要一个跨平台的解决方案，然而一个Windows只有一个是可以接受的。

I'm looking for a good reader/writer lock in C++. We have a use case of a single infrequent writer and many frequent readers and would like to optimize for this. Preferable I would like a cross-platform solution, however a Windows only one would be acceptable.

推荐答案

更新版本的 boost::thread 有读/写锁（1.35.0及更高版本，显然以前的版本无法正常工作）。

Newer versions of boost::thread have read/write locks (1.35.0 and later, apparently the previous versions did not work correctly).

它们的名称为 shared_lock ， unique_lock 和 upgrade_lock ，并操作 shared_mutex 。

They have the names shared_lock, unique_lock, and upgrade_lock and operate on a shared_mutex.
