对C ++和boost库来说非常新 我构建了一个简单的计时器机制 我的问题: 在第一个定时器运行调用timer.StartAppTimer(1,10);我收到处理程序消息 但是当我重新运行启动计时器时它说开始但是在10秒后我没有收到任何处理程序消息.. 请指导
以下是我的代码:
#include <iostream>
#include <windows.h>
#include <timer.h>
#define sleep(n) Sleep(1000 * n)
using namespace boost::posix_time;
using namespace std;
void handler1(int id,const boost::system::error_code &ec)
{
if (ec == boost::asio::error::operation_aborted)
{
std::cout << microsec_clock::local_time() << " Handler1: Timer 1 was cancelled or retriggered." << std::endl;
std::cout << "TIMER ID : " << id<< std::endl;
}
else
{
std::cout << microsec_clock::local_time() << " Handler1: expired." << std::endl;
std::cout << "fsm RECIEVE msgBuf : " << id<< std::endl;
}
}
Mytimer::Mytimer()
: m_pTimer(NULL),
m_pThread(NULL)
{
m_pTimer = new boost::asio::deadline_timer(io_service1);
}
void Mytimer::runTimerThread()
{
std::cout << "IO Service started " << std::endl;
io_service1.run();
}
void Mytimer::startTimer(int time,int timerId)
{
m_pTimer->expires_from_now(boost::posix_time::seconds(time));
m_pTimer->async_wait(boost::bind(handler1,timerId,boost::asio::placeholders::error));
m_pThread = new boost::thread(&Mytimer::runTimerThread, this);
}
void Mytimer::stopTimer()
{
io_service1.reset();
io_service1.stop();
}
bool Mytimer::isRunning()
{
time_duration td = m_pTimer->expires_from_now();
if (td.total_seconds() > 0)
{
return true;
}
return false;
}
void TimerAccess::StartAppTimer(int Timerid,int TimerPeriod){
std::cout << "TIMER ID : " << Timerid<< std::endl;
if (Timerid == APPTIMER1){
timer1.startTimer(TimerPeriod,Timerid);
}
if (Timerid == APPTIMER2){
timer2.startTimer(TimerPeriod,Timerid);
}
if (Timerid == APPTIMER3){
timer3.startTimer(TimerPeriod,Timerid);
}
}
void TimerAccess::StopTimer(int Timerid){
if (Timerid == APPTIMER1){
timer1.stopTimer();
}
if (Timerid == APPTIMER2){
timer2.stopTimer();
}
if (Timerid == APPTIMER3){
timer3.stopTimer();
}
// return -1;
}
int main()
{
cout << " before timer construction" << endl;
TimerAccess timer;
timer.StartAppTimer(1,10);
sleep(15);
cout << " before starting timer 2" << endl;
timer.StartAppTimer(1,10);
sleep(30);
cout << " END OF MAIN " << endl;
}
