There is an error in IM VI's  description of the File Manager routine
PBGetVolMountSize (Chapter: 25, Page: 48).

In the description of the parameter block it states that ioBuffer is a
pointer to long.  In fact, it is treated by the File Manager as a pointer
to short.  If you use the "size" it returns as a long and try to allocate
storage for that "size", you will wind up trying to allocate $A7xxxx bytes
instead of $A7 bytes, which is the size of a volume mounting record for an
AppleShare volume (currently).

Please let me know if I'm full of crap; and I'll take this opportunity to
say thanks to the DTS folks who frequent this group and take the time to
set us straight.

Cheers,
