WaitForSingleObject()函数有关问题

WaitForSingleObject()函数问题
我想要进行一段设置操作，这个操作有一部分少用的操作总是在重复，我想利用WaitForSingleObject()函数来设置一个时间段，这段时间内如果再进行这个设置操作，就不执行这个少用的操作部分，等待超时的时候再执行这段代码
所以我要问的是：WaitForSingleObject()的第一个参数句柄应该设置成什么事件的句柄，如何来操作这些，最好有代码，谢谢！

C/C++ code

HANDLE hMutex; // Create a mutex with no initial owner.hMutex = CreateMutex(     NULL,                       // default security attributes    FALSE,                      // initially not owned    NULL);                      // unnamed mutexBOOL FunctionToWriteToDatabase(HANDLE hMutex) {     DWORD dwWaitResult;     // Request ownership of mutex.     dwWaitResult = WaitForSingleObject(         hMutex,   // handle to mutex        5000L);   // five-second time-out interval     switch (dwWaitResult)     {        // The thread got mutex ownership.        case WAIT_OBJECT_0:             __try {                 // Write to the database.            }             __finally {                 // Release ownership of the mutex object.                if (! ReleaseMutex(hMutex))                 {                     // Deal with error.                }                 break;             }         // Cannot get mutex ownership due to time-out.        case WAIT_TIMEOUT:             return FALSE;         // Got ownership of the abandoned mutex object.        case WAIT_ABANDONED:             return FALSE;     }    return TRUE; }
