Parameters
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(). The function is valid only for nodes that correspond to files.
 
OUT PLARGE_INTEGER p__PLARGE_INTEGER__FileSizeInUCHARs 
Pointer to the variable to receive ISO9660 or Joliet file tree node file size in UCHARs. 
Returns

Execution status.

Description

This function returns ISO9660 or Joliet file tree file size in UCHARs.

Remarks

This call is identical to the StarBurn_ISO9660JolietFileTree_GetNodePowerInUCHARs(...) except it has a bit different semantics.

Example

This example allocates Joliet file tree, get root node, gets file size in UCHARs and destroys it (tree) after it's not needed any more.
