  class ScopedUnlock
A class that simplifies thread synchronization with a mutex. The constructor accepts a Mutex and unlocks it. The destructor locks the mutex. { public: inline ScopedUnlock(M& mutex, bool unlockNow = true): _mutex(mutex) { if (unlockNow) _mutex.unlock(); } inline ~ScopedUnlock() { _mutex.lock(); } 

  private:
          M& _mutex;
  
          ScopedUnlock();
          ScopedUnlock(const ScopedUnlock&);
          ScopedUnlock& operator = (const ScopedUnlock&);
  };
  
  } // namespace Poco
