IHUAPI.dll fetch only 100,000 Records

Question

I am using IHUAPI.dll in c#.net for fetching records from Proficy Historian Database. It gives me only 100,000 Records.

following is function i am using :

result= IHUAPI.ihuRetrieveSampledData(handle, tags, start, end,ihuSamplingMode.Trend,0, (uint)interval, out tagValues, out resultError);

I don't understand whether it is limitation of API or missing something ,Also i didn't find any docs related to this.

Anyone has gone through this ..!!

Thanks in advance.
