#include "Ltdic.h"

L_LTDIC_API pDICOMIOD L_DicomGetFirstIOD(pIOD, bTree)

Returns a pointer to the first item in the IOD Structure. The result depends on whether the IOD Structure is evaluated as a tree or a list.

Parameters

pDICOMIOD pIOD

Pointer to a DICOMIOD structure within the IOD Structure. A pointer to the DICOMIOD structure that contains the first item in the IOD Structure will be returned.

L_BOOL bTree

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

Returns

Comments

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

If the IOD Structure is evaluated as a list, the first item in the list is returned. Please note that the numbering of the items in this illustration does indicate the order of the items when the IOD Structure is evaluated as a list.

The following functions will also help you navigate the IOD Structure as either a tree or a list:

• L_DicomGetLastIOD
• L_DicomGetPrevIOD
• L_DicomGetNextIOD

If you evaluate the IOD Structure as a tree, you can also use the following functions to navigate the tree:

• L_DicomGetRootIOD
• L_DicomGetParentIOD
• L_DicomGetChildIOD
