We don't maintain a leaf node count, only a leaf record count? The BTree Header Record (BTHeaderRec, defined in HFSVolumes.h) maintains a count of the number of records contained in the leaf nodes of the tree (BTHeaderRec->leafRecords), as well as the total number of nodes allocated to the BTree file (BTHeaderRec->totalNodes), and the number of free nodes (BTHeaderRec->totalNodes). The leaf record count in the BTHeaderRec was getting out of synch in earlier version of MacOS X but I haven't seen that since Beta. Can we get the developer to clarify this? ---------------- Thanks, Peter On Thursday, November 2, 2000, at 01:47 AM, Halfmann, Klaus wrote: > I'm in the process of writing HFS+ tools for linux and currently > work at the hpfsck tool.
