Why?

What's wrong with PBHOpenRF?

According to IM IV p. 137:


"PBHOpenRF is identical to PBOpenRF except that it accepts a
directory ID in ioDirID."


FUNCTION PBHOpenRF (paramBlock: HParmBlkPtr; async: BOOLEAN) : OSErr;
 
Trap macro  _HOpenRF
 
Parameter block
    ->  12  ioCompletion    pointer
    <-  16  ioResult        word
    ->  18  ioNamePtr       pointer
    ->  22  ioVRefNum       word
    <-  24  ioRefNum        word
    ->  27  ioPermssn       byte
    ->  28  ioMisc          pointer
    ->  48  ioDirID         long word




I'm sorry if I'm missing some fundamental fact.
