Hello,

I just have a question regarding the size of the HFS Plus - Catalog Thread Record specified in the Apple Universal Interfaces headers -

typedef UInt16 UniChar;

/* HFSUniStr255 is the Unicode equivalent of Str255 */
struct HFSUniStr255 {
UInt16 length; /* number of unicode characters */
UniChar unicode[255]; /* unicode characters */
};

/* HFS Plus catalog thread record -- 264 bytes */
struct HFSPlusCatalogThread {
  UInt16                      recordType;             /* record type */
  UInt16                      reserved;               /* reserved - set to zero */
HFSCatalogNodeID    parentID;               /* parent ID for this catalog node */
HFSUniStr255           nodeName;               /* name of this catalog node (variable length) */
};
typedef struct HFSPlusCatalogThread     HFSPlusCatalogThread;

Based on the above declarations shouldn't the size for the HFSPlus catalog thread record be 2+2+4 (since CNID's are 4 bytes long ) + 256*2 = 264+256 instead of 264 as mentioned above ? I think someone probably forgot to multiply the 256 by 2 but I just wanted to make sure that is an error.

I'd be happy to hear some feedback from the list wrt this.

Best Regards,
