iostream和No_delay选项 [英] iostream and No_delay option
本文介绍了iostream和No_delay选项的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试使用相同问题的答案禁用Nagle算法: ASIO ip: :tcp :: iostream和TCP_NODELAY :
I am trying to disable the Nagle Algorithm using the answer for the same question: ASIO ip::tcp::iostream and TCP_NODELAY:
boost::asio::ip::tcp::iostream socketStream;
const boost::asio::ip::tcp::no_delay option( true );
socketStream.rdbuf()->set_option( option );
boost::asio::io_service io_service;
tcp::endpoint endpoint (tcp::v4 (), 6666);
tcp::acceptor acceptor (io_service, endpoint);
std::cout << "Waiting for connection.." << std::endl;
acceptor.accept (*socketStream.rdbuf ());
std::cout << "Connected!" << std::endl;
,并且在运行代码时出现此错误:
and when running the code this error appears:
set_option: Bad file descriptor
我该如何解决这个问题?
How can I solve this problem?
推荐答案
在设置选项的地方,流仍然无效(未打开).
Where you set the option, the stream is still invalid (not open).
在设置选项之前,请等待直到插座打开:
Wait until the socket is open, before setting the option:
#include <boost/asio.hpp>
#include <iostream>
static boost::asio::ip::tcp::no_delay const no_delay_option (true);
int main() {
using boost::asio::ip::tcp;
tcp::iostream socketStream;
boost::asio::io_service io_service;
tcp::endpoint endpoint (tcp::v4(), 6666);
tcp::acceptor acceptor (io_service, endpoint);
std::cout << "Waiting for connection.." << std::endl;
acceptor.accept (*socketStream.rdbuf ());
socketStream.rdbuf()->set_option(no_delay_option);
std::cout << "Connected!" << std::endl;
std::cout << socketStream.rdbuf() << "\n";
}
(我们在那里使用netcat将main.cpp
发送到端口6666)
(We send main.cpp
to port 6666 using netcat there)
