EOS_PT_EXTRACTPERIOD

EOS_PT_EXTRACTPERIOD

This function reads data from the designated level fields into the data buffer from the subsetted time period.

Examples


In this example, we read data within the subsetted time period defined by EOS_PT_DEFTIMEPERIOD from the Time field:

periodID = EOS_PT_DEFTIMEPERIOD(pointID, 35208757.6d, $
   35984639.2d)
IF (periodID NE -1) THEN BEGIN
   status = EOS_PT_EXTRACTPERIOD(pointID, periodID, 1, $
      "Time", buffer)
   HDF_UNPACKDATA, buffer, dataTime, HDF_TYPE=[6]
ENDIF

Syntax


Result = EOS_PT_EXTRACTPERIOD(pointID, periodID, level, fieldlist, buffer)

Return Value


Returns SUCCEED (0) if successful and FAIL (–1) otherwise.

Arguments


pointID

Point id (long).

periodID

Period id (long) returned by EOS_PT_DEFTIMEPERIOD.

level

Point level (0-based long).

fieldlist

List of fields (string) to extract.

buffer

A named variable that will contain the data buffer. This buffer is in packed format. Use HDF_UNPACKDATA to convert it into variables.
