HDF_SD_END

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.

Syntax

HDF_SD_END, SDinterface_id

Arguments

SDinterface_id

An SD interface ID as returned by HDF _SD_START.

Keywords

None

Examples

; 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.
