StarBurn SDK (Software Development Kit) | | |
__stdcall STARBURN_IMPEX_API PVOID StarBurn_ISO9660JolietFileTree_GetParent(IN PVOID p__PVOID__ISO9660JolietFileTree, IN PVOID p__PVOID__ISO9660JolietFileTreeNode);
Parameters | Description |
IN PVOID p__PVOID__ISO9660JolietFileTree | Pointer to the ISO9660 or Joliet file tree object that toolkit allocated during call to StarBurn_ISO9660JolietFileTree_Create(). |
IN PVOID p__PVOID__ISO9660JolietFileTreeNode | Pointer to the ISO9660 or Joliet file tree node object that is either result of previous tree node kids enumeration with StarBurn_ISO9660JolietFileTree_GetFirstKid() and StarBurn_ISO9660JolietFileTree_GetNextKid() or the result of call to StarBurn_ISO9660JolietFileTree_GetRoot(). |
Pointer to parent node. NULL if no parent node present (this is root node).
This function returns ISO9660 or Joliet file tree node parent pointer.
Parent node can be used to enumerate all the kids and walk down the tree.
This example allocates Joliet file tree, get root node, gets parent and destroys it (tree) after it's not needed any more.
