Boost.Asio线程安全 [英] Boost.Asio thread safety

问题描述

调用async_write&是否安全?当仅从一个线程调用io_service :: run()时，会从不同线程读取async_read吗? 谢谢！

Is it safe to call async_write & async_read from different threads in situation when io_service::run() was called from only one thread? Thank you!

推荐答案

文档对此很保守，说不".

The documentation is conservative on that and says "no".

但是我还是在我的linux程序之一中执行此操作，它似乎工作正常.深入研究boost/asio/detail/epoll_reactor.ipp表明，函数start_op()确实受到互斥锁的保护，因此我的信心得到了提高.

But I'm doing this anyway in one of my linux programs and it seems to work fine. Digging into boost/asio/detail/epoll_reactor.ipp shows that the function start_op() is indeed protected by a mutex, so my confidence is increased.

但是其他平台可能有所不同..

But other platforms may be different..
