C++多线程使用代码实例

     using namespace std; HANDLE hMutex = NULL;//互斥量 //线程函数 DWORD WINAPI Fun(LPVOID lpParamter) { for (int i = 0; i < 10; i++) { //请求一个互斥量锁 WaitForSingleObject(hMutex, INFINITE); cout << "线程显示" << endl; Sleep(1000); //释放互斥量锁 ReleaseMutex(hMutex); } return 0L;//表示返回的是long型的0 } int main() { //创建一个子线程 HANDLE hThread = CreateThread(NULL, 0, Fun, NULL, 0, NULL); hMutex = CreateMutex(NULL, FALSE, "screen"); //关闭线程 CloseHandle(hThread); //主线程的执行路径 for (int i = 0; i < 10; i++) { //请求获得一个互斥量锁 WaitForSingleObject(hMutex, INFINITE); cout << "主线程显示" << endl; Sleep(100); //释放互斥量锁 ReleaseMutex(hMutex); } return 0; }
