StarBurn SDK (Software Development Kit) | | |
__stdcall STARBURN_IMPEX_API PVOID StarBurn_ISO9660JolietFileTree_GetRoot(IN PVOID p__PVOID__ISO9660JolietFileTree);
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(). |
Pointer to root node. NULL if no root present.
This function returns ISO9660 or Joliet file tree root node pointer.
Root can be used to enumerate all the root node kids and walk down the tree. Attention! This function will return NULL if nothing was added to the tree by StarBurn_ISO9660JolietFileTree_Add() before.
This example allocates Joliet file tree, get root node and destroys it (tree) after it's not needed any more.
