C ++ 11 std :: threads和posix threads [英] C++11 std::threads vs posix threads

问题描述

为什么我应该在实践中偏好某一个？
除了std :: thread是一个类之外，什么是技术差异？

Why should I prefer one or another in practice? What are technical differences except that std::thread is a class?

推荐答案

许多平台，去Posix线程。他们几乎无处不在，而且相当成熟。另一方面，如果你只使用Linux / gcc std :: thread 是完全正确的 - 它有一个更高的抽象级别，一个非常好的接口，并与其他C + +11类。

If you want to run code on many platforms, go for Posix Threads. They are available almost everywhere and are quite mature. On the other hand if you only use Linux/gcc std::thread is perfectly fine - it has a higher abstraction level, a really good interface and plays nicely with other C++11 classes.

不幸的是，C ++ 11 std :: thread ）在每个平台上，即使C ++ 11似乎可用。例如在本地Android std :: thread 或Win64它只是不工作或有严重的性能瓶颈（2012年）。

The C++11 std::thread class unfortunately doesn't work reliably (yet) on every platform, even if C++11 seems available. For instance in native Android std::thread or Win64 it just does not work or has severe performance bottlenecks (as of 2012).

一个很好的替换是 boost :: thread - 它非常类似于 std :: thread 实际上是来自同一个作者）和工作可靠，但当然，它引入了另一个依赖从第三方库。

A good replacement is boost::thread - it is very similar to std::thread (actually it is from the same author) and works reliably, but, of course, it introduces another dependency from a third party library.
