我正在调整this example以检查邮件是否花了太长时间才能收到。
当read_complete
完成时,会调用 read_start
。但是,我必须检查,如果收到的数据是完整的,如果在给定时间内没有完全收到,则将其解释为不完整。
这些是我在代码/伪代码中对代码的扩展:
void read_complete(const boost::system::error_code& error, size_t bytes_transferred)
{ // the asynchronous read operation has now completed or failed and returned an error
if (!error)
{ // read completed, so process the data
cout.write(read_msg_, bytes_transferred); // echo to standard output
MyOnReceivedData(MyHandle someHandle, numOfBytes);
read_start(); // start waiting for another asynchronous read again
}
else do_close(error);
}
void MyOnReceivedData(MyHandle someHandle,int numOfBytes){
ResetPacketTimer();
\\check if whole packet was received
if (wholePacket){
MyOnReceivedPacket(someHandle);
}
}
void MyOnReceivedPacket(MyHandle someHandle){
cout << "packet"
clearBuffer(someHandle);
}
void MyOnPacketTimeout(MyHandle someHandle){
cout << "we're in";
if (!bufferEmpty(someHandle)){
cout << "timeout";
}
}
void ResetPacketTimer(MyHandle someHandle){
boost::asio::io_service io;
boost::asio::deadline_timer t(io, boost::posix_time::milliseconds(10000));
t.async_wait(boost::bind(&MyOnPacketTimeout, someHandle);
//this works async, but MyOnPacketTimeout is not called
boost::thread t2(boost::bind(&boost::asio::io_service::run, &io));
//this works, but not async - app waits for 10 secs
//io.run();
}
我确实在How can I setup a deadline_timer in this environment?说了一个类似的问题,但现在我已经让我的计时器正常工作了 - 这只是一个线程问题。所以,如果这是问题,请关闭旧问题,但请不要这个。
我的主要问题是,如何做ResetPacketTimer
,以便:
