Gets information about a working directory.

OSErr PBGetWDInfoSync (
    WDPBPtr paramBlock
);

paramBlock

A pointer to a working directory 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 output, a pointer to the volume’s name. You should pass a pointer to a Str31 value if you want that name returned. If you pass NULL, no volume name is returned.

• ioVRefNum

  A volume specification. The ioVRefNum field contains a working directory reference number when a working directory reference number is passed in that field; otherwise, it returns a volume reference number.

• ioWDIndex

  On input, an index.

• ioWDProcID

  The working directory user identifier.

• ioWDVRefNum

  On return, the volume reference number for the working directory. The ioWDVRefNum field always returns the volume reference number.

• ioWDDirID

  On output, the working directory’s directory ID.

The working directory can be specified either by its working directory reference number in ioVRefNum (in which case the value of ioWDIndex should be 0), or by its index number in ioWDIndex. In the latter case, if the value of ioVRefNum is not 0, it’s interpreted as a volume specification, and only working directories on that volume are indexed.
