Purpose
|
Deletes a tag and reference number from the data descriptor list. |
|
|
Return value
|
Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise. |
|
|
Description
|
Once the data descriptor is removed, the data in the data object becomes inaccessible and is marked as such. To remove inaccessible data from an HDF file, use the utility hdfpack. |
|
|
|
Hdeldd only deletes the specified tag and reference number from the data descriptor list. Data objects containing the deleted tag and reference number are not automatically updated. For example, if the tag and reference number deleted from the descriptor list referenced an object in a vgroup, the tag and reference number will still exist in the vgroup even though the data is inaccessible. |
