[Boost-users] Sample code for boost::thread - Timed Lockable mutex ?

21 Aug 2008

      Hello,

I want to use timed lockable mutex in boost::thread, but the usage is
not so obvious for a beginner.

Would there be anywhere a sample code with this kind og mutex ?

I have a code which works with a boost::mutex in a consumer/producer
queue (code below).
The purpose is to have a maximum waiting delay for waitForNotEmpty().

Thanks.

-------------------------------------------------------------------------

template <typename T>
class MTBornedQueue
{
public:
    ....
    bool waitForNotEmpty()
    {
        if (!m_container.empty())
            return true;

        boost::mutex::scoped_lock lock(m_accessMutex);
        m_notEmpty.wait(lock,
boost::bind(&MTBornedQueue<value_type>::isNotEmpty, this));
        return true;
    }
    ...

private:
    bool isNotEmpty() const { return m_unread > 0; };
    size_type            m_unread;
    container_type     m_container;
    boost::mutex        m_accessMutex;
    boost::condition    m_notEmpty;
}
