I see that we have a deadline timer in boost. I am looking for a periodic
timer. I see that there is a sample code in boost website to simulate a
periodic timer. Over a period of time I think it will probably cause some
slippage. I am looking at microsecond granularity Can someone please advise?
#include <iostream>
#include
#include
#include
#include
class printer
{
public:
printer(boost::asio::io_service& io)
: timer1_(io, boost::posix_time::microseconds(10)),
count_(0)
{
timer1_.async_wait(boost::bind(&printer::print1, this));
}
~printer()
{
std::cout << "Final count is " << count_ << "\n";
}
void print1()
{
if (count_ < 100)
{
timer1_.expires_at(timer1_.expires_at() +
boost::posix_time::microseconds(10));
timer1_.async_wait(boost::bind(&printer::print1, this));
std::cout << "Timer 1: " << count_ << "\n";
++count_;
}
}
private:
boost::asio::deadline_timer timer1_;
int count_;
};
int main()
{
boost::asio::io_service io;
printer p(io);
boost::thread t(boost::bind(&boost::asio::io_service::run, &io));
io.run();
t.join();
return 0;
}
