The HDF_SD_END procedure closes the SD interface to an HDF file. Failure to close the file without a call to HDF_SD_END results in the loss of any changed or added SD data. Therefore, HDF_SD_END calls should always be paired with calls to HDF_SD_START. Before HDF_SD_END is called, all access to SD datasets should be terminated with calls to HDF_SD_ENDACCESS.
HDF_SD_END, SDinterface_id
An SD interface ID as returned by HDF _SD_START.
None
; Open a new HDF file:
SDinterface_id = HDF_SD_START('test.hdf', /CREATE)
; Various commands could now be used to access SD data
; in the HDF file.
; When done with datasets, access should be ended with
; calls to HDF_SD_ENDACCESS:
HDF_SD_ENDACCESS, SDdataset_id_1
; When done with an HDF file, it should be closed:
HDF_SD_END, SDinterface_id
Another example can be seen in the documentation for HDF_SD_ATTRSET.
