### Data Members

## Class Description

     TVirtualMutex

     This class implements a mutex interface. The actual work is done via
     TMutex which is available as soon as the thread library is loaded.

     and

     TLockGuard

     This class provides mutex resource management in a guaranteed and
     exception safe way. Use like this:
     {
        TLockGuard guard(mutex);
        ... // do something
     }
     when guard goes out of scope the mutex is unlocked in the TLockGuard
     destructor. The exception mechanism takes care of calling the dtors
     of local objects so it is exception safe.
