And here is a simple mutex implementation for Windows:

class mutex
  { // recursive mutex using CriticalSection of Win32
    public:
      mutex()               { InitializeCriticalSection(&cs); }
      ~mutex()              { DeleteCriticalSection(&cs);     }
      void Lock()    { EnterCriticalSection(&cs);      }
      void Unlock()  { LeaveCriticalSection(&cs);      }
      bool TryLock() { return TryEnterCriticalSection(&cs) != 0; }
    private:
      CRITICAL_SECTION cs;
  };

class Locker
  {
    public:
      Locker(mutex& Am) : m(Am) { m.Lock();   }
      ~Locker()                 { m.Unlock(); }
    private:
      mutex& m;
  };
