Class Description

                                                                      
 TCondition                                                           
                                                                      
 This class implements a condition variable. Use a condition variable 
 to signal threads. The actual work is done via the TConditionImp     
 class (either TPosixCondition, TSolarisCondition or TNTCondition).   
                                                                      


TCondition(TMutex *m)
 Create a condition variable. The actual condition implementation
 will be provided via the TThreadFactory. If no external mutex is
 provided one will be created. Use GetMutex() to get this mutex
 and use it before calling Signal() or Broadcast().

~TCondition()
 Clean up condition variable.

TMutex* GetMutex() const
 Get internally created mutex. Use it to lock resources
 before calling Signal() or Broadcast(). Returns 0 if
 external mutex was provided in TCondition ctor.

Int_t Wait()
 Wait for to be signaled.

Int_t TimedWait(ULong_t secs, ULong_t nanoSec)
 Wait not more than secs+nanoSecs to be signaled.
