[asio-users] asio::deadline_timer does not call the handler if I change the time back

[niXman]

This simple code does not call the handler print () if I change the time back.
Is this normal?
How can I fix this behavior?

#include <iostream>
#include <boost/asio.hpp>

void print(const boost::system::error_code& /*e*/) {
std::cout << "Hello, world!" << std::endl;
}

int main() {
boost::asio::io_service io;

boost::asio::deadline_timer t(io, boost::posix_time::seconds(5));
t.async_wait(print);

io.run();
return 0;
}

Thanks.

This is an ancient question. I think it would be better if author of Asio adds the answer to the docs (for example, here http://www.boost.org/doc/libs/1_49_0/doc/html/boost_asio/overview/timers.html).

In short, the answer is:
http://www.boost.org/doc/libs/1_49_0/doc/html/boost_asio/reference/steady_timer.html

or (if you can't use the latest version of Boost.Asio) make it yourself (http://asio-samples.svn.sourceforge.net/viewvc/asio-samples/branches/steady_deadline_timer/include/ma/steady_deadline_timer.hpp?revision=509&view=markup inspired by http://www.boost.org/doc/libs/1_49_0/doc/html/boost_asio/example/timers/tick_count_timer.cpp)

Thank you for your answer.
