Deletes a module from the Data Set.
Module constant that specifies which module to delete. For a list of default values, refer to IOD Module Constants.
You can remove all items from the Data Set using LDicomDS::ResetDS.
Since the Data Set is stored internally as a tree, the deletion must be carried out as a tree.
When deleting an item from the tree, if the item being deleted has a sibling (same level, same parent), following it, this function returns a pointer to this sibling. If the item being deleted does not have a sibling following it, but has a sibling preceding it, this function returns a pointer to the preceding sibling. If the item being deleted is an only child, this function returns a pointer to the parent. If there is no parent this function returns NULL.
Below are illustrations of these situations:
For the sake of these illustrations, the order of siblings is top to bottom. A preceding sibling is drawn above the sibling it precedes, a following sibling is drawn below the sibling it follows.
NOTE: The numbering of the items of interest is arbitrary, and does not imply order.
In this illustration item 2 will be deleted. Since it has a following sibling, the returned pointer will point to item 3.
In this illustration item 3 will be deleted. Since it does not have a following sibling, but does have a preceding sibling, the returned pointer will point to item 2.
In this illustration item 2 will be deleted. Since it is an only child, the returned pointer will point to the parent, item 1.
In this illustration item 1 will be deleted. Since it has no siblings and no parent, this function will return NULL.
