This function updates the specified fields and records of a single level.
Result = EOS_PT_UPDATELEVEL(pointID, level, field, list, nrec, recs, data)
Returns SUCCEED (0) if successful and FAIL (–1) otherwise.
Point id (long) returned by EOS_PT_CREATE or EOS_PT_ATTACH.
Level to update (0-based long).
List of fields (string) to update.
Number of records (long) to update.
Record number of records to update (0-based long).
Values to be written to the fields. Data values are not converted to the internal HDF type automatically. Use HDF_PACKDATA if conversion is necessary or the data fields specify multiple types.
None
In this example, we update records 0, 2, and 3 in the Temperature and Mode fields in the second level in the point referred to by the point ID pointID. Temperature is a 4 value 32-bit float field and Mode is a 4 character field (HDF types 5 and 4 respectively):
recs = [ 0, 2, 3]
dataTemperature = [ [20, 21, 22, 23], [30, 31, 32, 33], $
[40, 41, 42, 43]]]
dataMode = ['P', 'I', 'A']
buffer = HDF_PACKDATA(dataTemperature, dataMode, $
HDF_TYPE = [5, 4], HDF_ORDER = [4, 4])
status = EOS_PT_UPDATELEVEL( pointID, 1, "Temperature,Mode", $
3, recs, buffer)
