Example

This example allocates CdvdBurnerGrabber object, creates and destroys UDF tree and destroys the device object after it's not needed any more.

// Prepare exception text buffer

// Prepare CDB failure information
RtlZeroMemory(

// Check for correct reply
if ( l__EXCEPTION_NUMBER != EN_SUCCESS )
{
// Handle error here...
}

// Add nodes with StarBurn_UDF_FormatTreeItemAsXxx here

// Create UDF tree with StarBurn_UDF_CreateEx() here

// Do something with the UDF tree here (maybe burn to CdvdBurnerGrabber object)

// Clean up UDF stuff with StarBurn_UDF_CleanUp() here

// Destroy UDF tree from the root
StarBurn_UDF_Destroy(
    &l__UDF_TREE_ITEM__Directory[ 0 ],
    &l__UDF_CONTROL_BLOCK
    );

// Destroy the CdvdBurnerGrabber
StarBurn_Destroy( &l__PVOID__CdvdBurnerGrabber );

// Just check for pointer (paranoid?)
if ( l__PVOID__CdvdBurnerGrabber != NULL )
{
// Handle error here...
}
