How to interrupt boost::this_thread in c++

Question

In my application i have given sleep of 10 sec. I have given sleep using boost::this_thread::sleep function. Is there any possible way to interrupt boost::this_thread::sleep function.?

@WouterHuysentruit, should you answer beeing funny? – Nidhoegger May 29 '15 at 11:46 — Nidhoegger, May 29 '15 at 11:46

From the sleep() reference:

Throws: boost::thread_interrupted if the current thread of execution is interrupted.

Notes: sleep() is one of the predefined interruption points.

So what you need to do in your thread is to put the sleep() call in a try-catch, and catch boost::thread_interrupted. Then call interrupt() on the thread object to interrupt the sleep.

By the way, also from the sleep reference:

Warning

DEPRECATED since 3.0.0.

Use sleep_for() and sleep_until() instead.

hey @Joachim Pileborg i m using sleep function from "boost::this_thread" which does not have interrupt API and my requirement is to use "boost::this_thread" so is there any way to interrupt sleep. – Mukul May 29 '15 at 11:55
@user3721279 `boost::this_thread::sleep` is, as I quoted from the link in my answer, an *interruption* point. Please read the links provided in my answer. – Some programmer dude May 29 '15 at 12:27

You can interrupt the sleep function using interrupt().

You have to enable interruption for your thread, when its sleeping, you can use the interrupt function.

Boost hast a very nice short tutorial online regarding this, have a look here: http://www.boost.org/doc/libs/1_54_0/doc/html/thread/thread_management.html#thread.thread_management.tutorial.interruption

Not as such, but it is not difficult to implement it, in terms of boost::this_thread::sleep:

void sleep_for(boost::posix_time::milliseconds interval, std::atomic<bool>& interrupted)
{
    static const auto resolution = boost::posix_time::milliseconds(10));
    ptime end_time(microsec_clock::local_time()) + interval;

    while( !interrupted.load() )
    {
        boost::this_thread::sleep(resolution);
        if(microsec_clock::local_time() > end_time)
            break;
    }
}

Client code thread 1:

std::atomic<bool>& interrupt = false;

void f() {
    sleep_for(boost::posix_time::milliseconds(200), interrupt);
}

Client code thread 2:

interrupt.store(true); /// will cause thread 1 to be interrupted, if called
                       /// during execution of sleep_for.
