Discussion

HDFGETSDS obtains the current Scientific Data Set in an HDF file and positions the active pointer to the next SDS. This function is preferred for getting Scientific Data Sets, as it automatically dimensions and casts a PV-WAVE array prior to obtaining the actual data.

Example

data = 0
status = DFSDrestart ()
IF (status EQ FAIL) THEN  $
    MESSAGE, 'Failed DFSDrestart for'+ '  HDFGETSDS.'
status = HDFGETSDS (testfile, data, Maxrank=100)
IF (status EQ FAIL) THEN  $
    MESSAGE, 'HDFGETSDS failed.'
