您可以设置在升压ASIO SO_RCVTIMEO和SO_SNDTIMEO套接字选项？ [英] can you set SO_RCVTIMEO and SO_SNDTIMEO socket options in boost asio?

问题描述

您可以在升压ASIO设置SO_RCVTIMEO和SO_SNDTIMEO套接字选项？

can you set SO_RCVTIMEO and SO_SNDTIMEO socket options in boost asio?

如果又如何？

请注意，我知道你可以使用定时器来代替，但我想知道，特别是以下套接字选项。

Note I know you can use timers instead, but I'd like to know about these socket options in particular.

推荐答案

当然！提高ASIO允许您访问本机/基础数据，在这种情况下是插座本身。所以，让我们说你有：

Absolutely! Boost ASIO allows you to access the native/underlying data, which in this case is the SOCKET itself. So, let's say you have:

boost::asio::ip::tcp::socket my_socket;

和假设你已经叫打开或绑定或实际上使一些成员函数 my_socket 使用。然后，为了获取潜在的SOCKET值，调用：

And let's say you've already called open or bind or some member function that actually makes my_socket usable. Then, to get the underlying SOCKET value, call:

SOCKET native_sock = my_socket.native();
int result = SOCKET_ERROR;

if (INVALID_SOCKET != native_sock)
{
    result = setsockopt(native_sock, SOL_SOCKET, <the pertinent params you want to use>);
}

所以你有它！ Boost的ASIO让你更快地比，否则你也许可以做很多事情，但也有很多事情，你仍然需要正常的套接字库的调用。这恰好是其中之一。

So there you have it! Boost's ASIO lets you do many things more quickly than you otherwise might be able to, but there are a lot of things you still need the normal socket library calls for. This happens to be one of them.
