static pDICOMIOD LDicomIOD::GetChild(pIOD)
Returns a pointer to the item in the IOD Structure that contains the first child of the specified item.
Pointer to a DICOMIOD structure that contains an item in the IOD Structure.
Value | Meaning |
---|---|
!NULL | A pointer to a DICOMIOD structure that contains the item in the IOD Structure that is the first child of the item specified in pIOD. |
NULL | pIOD has no child items. |
This function requires that the IOD Structure is evaluated as a tree structure.
The child is the offspring one level lower than the specified item. If the specified item has no child items, this function will return NULL. For example:
If the passed pointer points to | The function returns a pointer to |
---|---|
Item 1 | NULL |
Item 2 | Item 3 |
Item 4 | Item 5 |
Item 6 | NULL |
