L_LTDIC_API pDICOMIOD L_DicomGetLastIOD(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 last item in the IOD Structure. The result depends on whether the IOD Structure is evaluated as a list or a tree.

Parameter Description
pIOD Pointer to a DICOMIOD structure within the IOD Structure. A pointer to the DICOMIOD structure that contains the last 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 last 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 last 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.

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

L_DicomGetFirstIOD

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

Example

The first example displays the name of the last item in the current level. The second example displays the name of the last item in the IOD table.

L_INT DicomGetLastIODExample1(L_VOID) 
{ 
   pDICOMIOD pElement; 
   pDICOMIOD pLast; 
   pElement = L_DicomFindIOD(NULL, TAG_PATIENT_NAME, IOD_TYPE_ELEMENT, FALSE); 
   if (pElement != NULL) 
   { 
      pLast = L_DicomGetLastIOD(pElement, TRUE); 
      MessageBox(NULL, pLast->pszName, TEXT("Notice"), MB_OK); 
   } 
   return DICOM_SUCCESS; 
} 
L_INT DicomGetLastIODExample2(L_VOID) 
{ 
   pDICOMIOD pLast; 
   pLast = L_DicomGetLastIOD(NULL, FALSE); 
   if (pLast != NULL) 
      MessageBox(NULL, pLast->pszName, TEXT("Notice"), MB_OK); 
   return DICOM_SUCCESS;
