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 and StarBurn_ISO9660JolietFileTree_BuildImage was applied to later.
 
p__PULONG__HighPartSizeInUCHARs 
Pointer to the 32-bit unsigned long that will receive high part of 64-bit image size. 
Returns

Built ISO9660 or Joliet file system image size in UCHARs. This function cannot fail.

Description

This function returns ISO9660 or Joliet built file system image size in UCHARs.

Remarks

Used to determine the size of the built file system image so it will be clear will it fit on the CD/DVD/Blu-Ray/HD-DVD media (if burning) or on hard disk (if storing file system image as file on the disk) or not.

Example

This example allocates Joliet file tree from the directory, builds file system image, gets file system image size in UCHARs, checks for compatibility and destroys the file tree after it's not needed any more.
