从Boost.Asio的套接字类拆本地插座 [英] Detaching a native socket from Boost.ASIO's socket class

问题描述

是否有可能拆离Boost.Asio的套接字类本地插座？如果是这样，怎么能做到呢？我似乎无法找到任何文档中显而易见的。

Is it possible to detach a native socket from Boost.ASIO's socket class? If so, how can it be done? I can't seem to find anything obvious in the documentation.

由于什么，我试图完成的快速概览：我有一个类，使一个连接，并通过做一些Boost.Asio的谈判，然后传回上失败是成功还是0本机Windows SOCKET

As a quick overview of what I'm trying to accomplish: I have a class that makes a connection and does some negotiation using Boost.ASIO, then passes back a native Windows SOCKET on success or 0 on failure.

除非我弄错了，本机接口将被关闭，当我的boost :: ASIO :: basic_socket遭到破坏释放。

Unless I'm mistaken, the native socket will be closed and deallocated when my boost::asio::basic_socket is destructed.

推荐答案

回答我的问题。

Windows有一个WSADuplicateSocket功能，它可以用来复制本机插口。直到此套接字的所有描述符被释放底层套接字将继续开放。

Windows has a WSADuplicateSocket function, which can be used to duplicate the native socket. The underlying socket will remain open until all descriptors for this socket are deallocated.
