This function returns information about a subsetted time period for a particular fieldlist.
Result = EOS_PT_PERIODINFO(pointID, periodID, level, fieldlist, size)
Returns SUCCEED (0) if successful and FAIL (–1) otherwise.
Point id (long).
Period id (long) returned by EOS_PT_DEFTIMEPERIOD.
Point level (0-based long).
List of fields (string) to extract.
A named variable that will contain the size in bytes (long) of subset period.
None
In this example, we get the size of the subsetted time period defined in EOS_PT_DEFTIMEPERIOD for the Time field:
status = EOS_PT_PERIODINTO(pointID, periodID, 0, "Time", size)
