What I meant was, can you post a complete sample that you have actually compiled and run and that has actually demonstrated the problem? That obviously isn't the case with the code you posted because it contains syntax errors and the main() function in your second post doesn't match the definition of the testCommand class in your first post. Having said that, I fixed the errors the best I could and don't see the problem. It would help if you could: 1) Tell me what compiler and compiler version you're using. 2) Tell me what Boost version you're using. 3) Post a complete code sample that demonstrates the problem. 4) Specify what compile and link options you're using (perhaps you could attach a make file or project file?) Sorry; I'm trying to help, but if you want me to be able to figure out the problem you'll have to help me out.

The rest of the applicatin is just creating the object and preparing it for execution. I am using Win32 version of boost.Thread implementation.

The creation code snipet is

void main() { testCommand *tObj = new testCommand(11); tObj->createthread(); tObj->runthread(); }

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.

Thanks,

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_opsboost::mutex::unlock(boost::mutex & {...}) line 49 boost::detail::thread::scoped_lockboost::mutex::unlock() line 85 + 11 bytes

boost::detail::thread::scoped_lockboost::mutex::~scoped_lock

...

() line 74 `anonymous namespace'::thread_param::started() line 47 + 15 bytes thread_proxy(void * 0x0012fd74) line 71 _threadstartex(void * 0x00961040) line 212 + 13 bytes KERNEL32! 7c57b382()

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
