I am using the following code to detect whether the service is running on the machine or not, it needs to infinitely, so i have used infinite loop here, but the problem is the exe is taking more memory and it keeps on increasing for every second, How to solve this.

ENUM_SERVICE_STATUS EnService[512];
		SC_HANDLE ScManager,ScService; //Handle of service manager
		DWORD cbBufSize=512*sizeof(ENUM_SERVICE_STATUS); 
		DWORD lpServicesReturned; 
		DWORD pcbBytesNeeded; 
		DWORD lpResumeHandle=0; 
		 
		//For querying service info
		DWORD dwBytesNeeded;
		//LPQUERY_SERVICE_CONFIG lpqscBuf; 
		 
		//Open the service manager with all as desired access
		ScManager = OpenSCManager(NULL,NULL,SC_MANAGER_ALL_ACCESS); 
		 
		char szStatus[255];
		char szStartType[255];
		 
		if(ScManager==NULL) {
		printf("Error querying the service manager");
		return 0; 
		}
		 
		if(::EnumServicesStatus(
		ScManager,//Service manager Handle
		SERVICE_WIN32, //Service type To be retrieved
		SERVICE_STATE_ALL, //Retrive all windows services
		EnService, //Our buffer 
		cbBufSize, //Buffer size
		&pcbBytesNeeded, //number of bytes needed
		&lpServicesReturned, //number of services returned
		&lpResumeHandle //Resume handle (if any)
		)==0){
		printf("Error querying the service manager");
		return 0; 
		}
		 
		
		if((ScService=::OpenService(ScManager,_T("MYSQL"),SERVICE_ALL_ACCESS))==NULL)
		{
		printf("Error opening service");
		}
		 
		//Allocate some memory in our buffer for the actual querying
		/*lpqscBuf = (LPQUERY_SERVICE_CONFIG) LocalAlloc(LPTR, 4096); 
		if (lpqscBuf == NULL) 
		{
		printf("Error allocating service query");
		sprintf(szStartType,"Unknown");
		}
		 
		//Retrieve the configuration info
		if (! QueryServiceConfig( 
		ScService, 
		lpqscBuf, 
		4096, 
		&dwBytesNeeded) ) 
		{
		printf("Error querying service info");
		sprintf(szStartType,"Unknown");
		}*/
