L_LTDIC_API pDICOMIOD L_DicomGetNextIOD(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 item in the IOD Structure that immediately follows the specified item.

Parameter	Description
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.
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 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.

If the passed pointer points to :	The function returns a pointer to :
Item 1	Item 2
Item 3	Item 4
Item 5	NULL
Item 6	Item 7

If the IOD Structure is evaluated as a list, the next 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.

If the passed pointer points to :	The function returns a pointer to :
Item 14	Item 15
Item 4	Item 5
Item 8	Item 9
Item 19	Item 20
Item 27	Item 28
Item 30	NULL

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

L_DicomGetFirstIOD

L_DicomGetPrevIOD

L_DicomGetLastIOD

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

This example displays in a list-box control all classes from the IOD table

L_INT DicomGetNextIODExample(HWND hDlg) 
{ 
   pDICOMIOD pIOD; 
   pIOD = L_DicomGetFirstIOD(NULL, TRUE); 
   while (pIOD != NULL) 
   { 
      SendMessage(hDlg, LB_ADDSTRING, (WPARAM)0, (LPARAM)(LPCTSTR)pIOD->pszName); 
      pIOD = L_DicomGetNextIOD(pIOD, TRUE); 
   } 
   return DICOM_SUCCESS; 
}
