Changes the default volume and default directory.

OSErr PBSetVolAsync (
    ParmBlkPtr paramBlock
);

paramBlock

A pointer to a basic File Manager parameter block.

function result

A result code.

DISCUSSION

The relevant fields of the parameter block are:

• ioCompletion

  On input, a pointer to a completion function.

• ioResult

  On output, the result code of the function.

• ioNamePtr

  On input, a pointer to a pathname.

• ioVRefNum

  On input, a volume reference number or a working directory reference number.

If you pass a volume reference number in ioVRefNum, the PBSetVolAsync function makes the specified volume the default volume and the root directory of that volume the default directory. If you pass a working directory reference number, PBSetVolAsync makes the specified directory the default directory, and the volume containing that directory the default volume.
