OK. I am getting a mutex lock like this...

boost::mutex::scoped_lock  lock(mMutex);

where

boost::mutext mMutex

Now how do I check the status of the lock (if lock was gain or not). Some true/false status is fine. How do I do that in boost?

Using this lock it will always be gained. If you want the option to take a different action if it's not possible you need to use the try lock.

boost::mutex::scoped_try_lock  lock(mMutex);
bool locked = lock.owns_lock();
