是你的文章啊，昨天剛看完，很好的一篇文章，我來提一個問題
文中這處代碼：
template <class LOCK>
class Guard {
public:
// Store a pointer to the lock and acquire the lock.
Guard (LOCK &lock)
:m_pLlock (&lock), m_bOwner (false) {
m_pLlock->acquire ();
m_bOwner = true;
}
// Release the lock when the guard goes out of scope,
// but only if <acquire> succeeded.
virtual ~Guard () {
if (m_bOwner) m_pLlock->release ();
}
private:
// Pointer to the lock we're managing.
LOCK *m_pLlock;
// Records if the lock is held by this object.
bool m_bOwner;
// ... maybe need disallow copying and assignment ...
};
析構函數這里我有個疑問，是不是應該再加上m_bOwner = false;  回復  更多評論
  

呵呵，再看了下，我這句好像沒有啥用的，不過還是喜歡加這么句，  回復  更多評論
