【问题描述】:
我的问题是关于等待由 same 函数表示的某些操作完成的运行期限计时器:但我不知道,在安全完成后在哪里释放我的线程和期限对象oder 在截止日期超时之前中断。什么时候会发生这种情况?
boost::asio::deadline_timer* mDeadline1;
boost::asio::deadline_timer* mDeadline2;
boost::thread* mThread1;
boost::thread* mThread2;
// start deadline timers
mDeadline1 = new boost::asio::deadline_timer(_io_service, boost::posix_time::seconds(2));
mDeadline1->async_wait(&MyClass::DeadlineTimedOut, this);
mDeadline2 = new boost::asio::deadline_timer(_io_service, boost::posix_time::seconds(2));
mDeadline2->async_wait(&MyClass::DeadlineTimedOut, this);
// Run operations in threads
mThread1 = new boost::thread(&MyClass::DoSomething, this);
mThread2 = new boost::thread(&MyClass::DoSomething, this);
// ...
void MyClass::DoSomething() {
// Do something time expensive and sleep, etc. for interrupt point ...
// which to cancel here!?
mDeadline->cancel();
delete mDeadline;
}
void MyClass::DeadlineTimedOut(const boost::system::error_code& pErrorCode) {
if(pErrorCode == 0) { // deadline timed out
// which to interrupt here?
mThread->interrupt();
}
if(pErrorCode == 995) { // deadline cancelled from outside
}
}
有人给点建议吗?优雅,B.
