epoll重新注册：文件存在
当我尝试在断开连接后立即重新连接客户端时，在服务器端（带有fork（）的多进程服务器）上发生了此异常。我正在使用boost，但是现在我不明白引发异常的确切指令，因为在多进程中调试对我而言并不简单。
但是我想在这一点上：
io_service_.notify_fork(boost::asio::io_service::fork_child);
if (fork() == 0) //I\'m child process
{
io_service_.notify_fork(boost::asio::io_service::fork_prepare);
cout << \"I\'m child process and my PID is \" << getpid() << endl;
/*Notifies to the io_service_ the fork termination*/
try
{
io_service_.notify_fork(boost::asio::io_service::fork_child);
}
catch (boost::exception& e)
{ cout<<\"Exception in notify_fork child \"<< endl;
std::cerr << diagnostic_information(e) << std::endl;
}
/*Closes the listen socket which remains opened in the parent process to accept new connections*/
acceptor_.close();
}
else //I\'m the parent process
{
cout << \"I\'m the parent process and my PID is \" << getpid() << endl;
/*Notifies to the io_service_ the fork termination*/
try
{
io_service_.notify_fork(boost::asio::io_service::fork_parent);
}
catch (boost::exception& e)
{
cout<<\"Exception in notify_fork parent \"<< endl;
std::cerr << diagnostic_information(e) << std::endl;
}
socket_.close();
/*Listening to new connections*/
start_accept();
}
