It would be a lot easier to help if you could post a complete, compilable example that demonstrates the problem. Also, it would be useful to know whether you are using the Win32, pthread, or Mac implementation of Boost.Thread.

I am creating a boost thread, how to know in which state it is created. I have a code snippet that is waiting always in the thread creatin functon istelf. Where as i tried with some boost samples, they are working amazingly perfect. This is how my code snippet looks like
typedef boost::mutex::scoped_lock lock; class testCommand { static void threadfunc() { testCommand *testObj = mMapCommand[mObjID]; testObj->processthread(); };
static map< int mObjID, testCommand*> mMapCommand; private: void createthread() { mThread = new boost::thread(&testCommand::threadfunc); } void processthread() { lock lk(mMutex); mCondition.wait(lk); //// Some Action };
void runthread() { lock lk(mMutex); mCondition.notify_one(); };
public: static int mObjID; boost::thread *mThread; boost::condition mCondition; boost::mutex mMutex; };
The newly created thread is waiting at the following location forever, by the time i get a chance to execute the new thread is greatly delayed.
NTDLL! 77f8856e() boost::detail::thread::lock_ops<boost::mutex>::unlock(boost::mutex & {...}) line 49 boost::detail::thread::scoped_lock<boost::mutex>::unlock() line 85 + 11 bytes
boost::detail::thread::scoped_lock<boost::mutex>::~scoped_lock<boost:: mutex>

It sounds like i am missing something here. The queries here are 1. why it is waiting at the above specified line forever ? 2. Where can i get few worth thread samples done using boost::thread
