The purpose of this class is to enumerate NT services on a local machine. You can specify the following criteria for service enumeration:

• Do you want to enumerate NT services or NT drivers.
• Do you want to enumerate active or inactive services and or drivers.

Since the criteria is a bit OR combination, you can specify none, one of criterias or all of them. In any case, you will receive a list of NT services that fullfil the specified criteria.

The class is designed to work with STL classes. In fact, there are 2 EnumServices functions. One that returns a pointer to a list of objects (in this case caller is responsible to delete this pointer using delete []) and another that returns an STL list containing service objects.

Sample using STL list

TNtServiceInfoList srvList;
TNtServiceInfo::EnumServices(SERVICE_WIN32, SERVICE_ACTIVE, &srvList);
TNtServiceInfoList::iterator it;
for (it = srvList.begin(); it != srvList.end(); it ++) 
{
   TNtServiceInfo *pInfo = &(*it);
   // Do something

}
