CreatThread函式如下圖所示

在這裡我們只用到了第三個和第四個引數，第三個引數傳遞了一個函式的地址，也是我們要指定的新的執行緒。第四個引數是傳給新執行緒的引數指標。

int time = 0;

	HANDLE hThread1  = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)ThreadProc1,NULL,0,0);
	CloseHandle(hThread1);

HANDLE CreateMutex( 

 LPCTSTR);

Parameters

lpMutexAttributes

[in] Ignored. Must be NULL.

bInitialOwner

[in] Boolean that specifies the initial owner of the mutex object. If this value is TRUE and the caller created the mutex, the calling thread obtains ownership of the mutex object. Otherwise, the calling thread does not obtain ownership of the mutex. To determine if the caller created the mutex, see the Return Values section.

lpName

[in] Long pointer to a null-terminated string specifying the name of the mutex object. The name is limited to MAX_PATH characters and can contain any character except the backslash path-separator character (\). Name comparison is case sensitive.

If lpName matches the name of an existing named mutex object, the bInitialOwner

parameter is ignored because it has already been set by the creation process.

If lpName is NULL, the mutex object is created without a name.

If lpName matches the name of an existing event, semaphore, or file-mapping object, the function fails and theGetLastError function returns ERROR_INVALID_HANDLE. This occurs because these objects share the same name space. 

HANDLE hMutex;
void ThreadProc1()
{
	int hour = 0;
	int mins = 0;
	while(1)
	{
		WaitForSingleObject(hMutex, INFINITE);
		hour = time/60;
		mins = time%60;
		
		int day = hour/24;
		
		if (day)
		{
			hour -=day*24;
		}
		time++;
		
		printf("執行緒1 %d:%d\n",hour,mins);
		Sleep(1000);
		ReleaseMutex(hMutex);
	   // system("cls");
	}
