CCriticalSection() 能够发现这个类的构造函数没有參数，所以创建一个CCriticalSection类的对象很easy，仅仅有例如以下就可以： CCriticalSection criticalSection...1.创建单文档应用程序； 2.在视图类的实现文件里定义一个临界段对象： CCriticalSection criticalSection; 3.在视图类的实现文件里定义两个线程函数：...UINT MessageThread1(LPVOID pParam) { criticalSection.Lock(); LPTSTR pMessage =...AfxGetMainWnd(); ::MessageBox(pMainWnd->m_hWnd, pMessage, _T( “Thread message”), MB_OK); criticalSection.Unlock...(); return 0; } UINT MessageThread2(LPVOID pParam) { criticalSection.Lock();

在Log类成员里声明一个CRITICAL_SECTION对象criticalSection，初始化时： InitializeCriticalSection(&criticalSection); 当然，最好在释放资源时加上下述代码...： DeleteCriticalSection(&criticalSection); 而在进入writeLog时和离开writeLog时加上下述代码： int LOG::writeLog(...) {...int ret = 0; EnterCriticalSection(&criticalSection); // do something LeaveCriticalSection...(&criticalSection); return 0; } 需要提及的是，最好是在LeaveCriticalSection之后再DeleteCriticalSection。
CCriticalSection Gsz_CriticalSection; 第三步：在视图里的实现文件里面 定义这两个函数。这两个函数带回会被指定为线程函数。这两个函数不是视图类的成员函数。...UINT MessageThread1(LPVOID pParam) { Gsz_CriticalSection.Lock(); LPTSTR pMessage = _T("Thread1...pMainWnd = AfxGetMainWnd(); ::MessageBox(pMainWnd->m_hWnd, pMessage, _T("Thread message"), MB_OK); Gsz_CriticalSection.Unlock...(); return 0; } UINT MessageThread2(LPVOID pParam) { Gsz_CriticalSection.Lock(); LPTSTR pMessage...pMainWnd = AfxGetMainWnd(); ::MessageBox(pMainWnd->m_hWnd, pMessage, _T("Thread message"), MB_OK); Gsz_CriticalSection.Unlock

现在推出alpha 版本 利用新的 tf.contrib.data.SqlDataset，支持把一个 sqlite 数据库作为 Dataset 对象进行读入 tf.contrib.framework.CriticalSection...添加分布式的 Mutex /CriticalSection tf.regex_replace 更好地支持文本处理 tf.contrib.data.bucket_by_sequence_length

bfloat16，而不是 float32； 增加了 tf.contrib.image.connected_components； 增加了可让原子变量访问的 tf.contrib.framework.CriticalSection
readprocessmemory和writeprocessmemory的参数，但不知读取偏移即a+($b),b是怎么读的 一 、用hook全局钩子 线程钩子：已实现 使用INLINE hookapi，CriticalSection
fn barrier(); /// 临界区保护函数 fn free(f: F) -> R where F: FnOnce(&CriticalSection
mutex.lock(); } ~ScopedLock() { mutex.unlock(); }private: std::mutex& mutex;};void criticalSection
示例代码 class CriticalSection { private int count = 0; public void increment() { synchronized
synchronized (this) { criticalSection(); } 5.
这个过程实际上是通过限制有且只有一个函数进入CriticalSection变量来实现代码段同步的。
优化前： std::mutex mtx; void processData() { std::lock_guard lock(mtx); // 临界区代码 criticalSection...(); // 非临界区代码 nonCriticalSection(); } 优化后： std::mutex mtx; void processData() { criticalSection...(); // 非加锁部分 { std::lock_guard lock(mtx); criticalSection(); // 临界区代码
