I do quite a few things with the IHUAPI like Migrate data from one Historian to another, query data into clients, etc. Now I am trying to create a tag, but cannot seem to figure it out. The only thing I see in the IHUAPI is the following:

[DllImport(DLLNAME, CallingConvention = CallingConvention.StdCall, EntryPoint = "ihuTagAdd@4")]
public static extern ihuErrorCode ihuTagAdd(int serverhandle);

How would I use that to add a tag when serverhandle is the only parameter? I’m sure there is a way to do this, but I have been struggling to figure it out.
