Displaying a Critical Section

 临界区和MUTEX都可重入，但临界区owner退出后不会释放,而后者会自动释放

 

	CRITICAL_SECTION cs;
DWORD __stdcall	Threadtest(PVOID pp)
{
	printf("geting lock thread\n");
	EnterCriticalSection(&cs);
		EnterCriticalSection(&cs);可重入
	printf("get lock thread\n");
	/*Sleep(2000);*/
	MessageBoxA(NULL, "hh", NULL, NULL);

　　　　、、没释放
	printf("leave lock thread\n");
	return 1;
}


int _tmain(int argc, _TCHAR* argv[])
{
	InitializeCriticalSection(&cs);
	CreateThread(NULL, 0, Threadtest, NULL, NULL, NULL);
	Sleep(100);
		printf("geting lock _tmain\n");
		EnterCriticalSection(&cs);

临界区可重入，owner退出后不会释放
