难道是线程安全调用async_send和async_receive在同一时间？ [英] Is it thread safe to call async_send and async_receive at the same time?

问题描述

我了解，调用提高:: ASIO ::知识产权:: TCP ::插座:: async_receive （或的boost :: ASIO :: IP :: TCP ::插座:: async_send ）两次可能会导致不良行为..
它是确定的，如果我叫的boost ::支持ASIO ::知识产权:: TCP ::插座:: async_recive 和提高:: ASIO :: IP： ：？TCP套接字:: :: async_send 同时

I understood that calling boost::asio::ip::tcp::socket::async_receive (or boost::asio::ip::tcp::socket::async_send) two times may result in a bad behavior.. Is it OK if i call boost::asio::ip::tcp::socket::async_recive and boost::asio::ip::tcp::socket::async_send at the same time?

我将有2个或多个线程运行的boost ::支持ASIO ::运行所以你需要考虑到这一点。

I am going to have 2 or more threads running the boost::asio::run so you need to take that into account..

感谢

推荐答案

这必须是确定。你怎么回事就在一个单一的服务进行全双工异步通信？你需要一个在任何时候传入数据接收突出。

This has to be OK. How else would you perform full duplex async communications on a single service? You need a receive outstanding at all times for incoming data.

借助加速文档仅指示每个 async_read 和 async_write 必须连续调用。例如， async_read ：

The Boost docs indicate only that each of async_read and async_write must be called serially. For example, for async_read:

程序必须保证
  流不执行任何其他读
  操作（如async_read，该
  流的async_read_some功能，或
  任何其他操作组成的那
  执行读取），直至该操作
  完成。

The program must ensure that the stream performs no other read operations (such as async_read, the stream's async_read_some function, or any other composed operations that perform reads) until this operation completes.

为插座的文档不特定在这一点上，这是真的。

The docs for socket are not specific on this point, it's true.
