L_LTDIC_API pDICOMIOD L_DicomGetNextIOD(pIOD, bTree)

Returns a pointer to the item in the IOD Structure that immediately follows the specified item.

Parameters

pDICOMIOD pIOD

Pointer to a DICOMIOD structure that contains an item in the IOD Structure. A pointer to the item in the IOD Structure that immediately follows this item will be returned.

L_BOOL bTree

Flag that indicates how the IOD Structure will be evaluated. Possible values are:

Value Meaning
TRUE Evaluate the IOD Structure as a tree.
FALSE Evaluate the IOD Structure as a list.

Returns

Value Meaning
!NULL A pointer to a DICOMIOD structure that contains the item in the IOD Structure that immediately follows the item specified in pIOD.
NULL There is not an item following pIOD. (pIOD is the last item in the IOD Structure.)

Comments

If the IOD Structure is evaluated as a tree structure, this function returns the next item on the same level as pIOD with the same parent as pIOD. Please note that the numbering of the items in this illustration is arbitrary and does not imply order.
