L_LTDIC_API pDICOMIOD L_DicomGetFirstIOD(pIOD, bTree)

pDICOMIOD pIOD;

pointer to a DICOMIOD structure

L_BOOL bTree;

flag that indicates how to evaluate the IOD Structure

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.

Parameter Description
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.
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

!NULL

A pointer to a DICOMIOD structure that contains the first item in the IOD Structure.

NULL

The IOD Structure is empty.

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.

Item 5

Item 5

Item 6

Item 7

NULL

Item 2

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
