// our CSingleLock object.
CSingleLock singleLock(&m_Mutex);
// Attempt to lock the shared resource
singleLock.Lock(100); // Wait 100 ms...
// Has the resource been successfully locked?

// we may now work with the data associated with the mutex...
// Now that we are finished, unlock the resource for others.
