C++ 中的读/写锁

问题描述

我正在寻找一个好的 C++ 读写锁.我们有一个用例，有一个不频繁的作者和许多频繁的读者，并希望为此进行优化.最好我想要一个跨平台的解决方案，但是只有一个 Windows 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

较新版本的 boost::thread 具有读/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).

他们的名字是shared_lock、unique_lock 和 upgrade_lock 并对 shared_mutex.

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