用于c ++ 11线程的RW锁 [英] A RW lock for c++11 threads

问题描述

我想使用新的标准线程，而不是boost：线程，但我注意到旧的shared_mutex不可用。

I'd like to use the new standard threads instead of boost:threads but I've noticed the old shared_mutex is not available. What would be a good recommendation to replace this functionality and give me a multiple-readers, single-writer lock?

推荐答案

std :: shared_mutex 将是C ++ 14标准库的一部分。

std::shared_mutex will be part of the C++14 Standard Library. It did not make it to C++11 just because there was no time to formulate a proposal and discuss it thoroughly.

你仍然可以使用，因为它没有时间来创建一个提案， boost :: shared_mutex 虽然。在Windows下，如果您使用的是Windows Vista或更高版本，则可以使用 Slim读写锁定，它们针对速度和内存消耗进行了优化。

You can still use boost::shared_mutex though. Under Windows, if you are working with Windows Vista or later, you can use Slim Read-Write Locks, which are optimized for speed and memory consumption.
