Low-Level HFS Routines / Maintaining Working Directories

PBCloseWD
You can use the PBCloseWD function to close a working directory.
FUNCTION PBCloseWD (paramBlock: WDPBPtr; async: Boolean): OSErr;
paramBlock
A pointer to a working directory parameter block.
async
A Boolean value that specifies asynchronous (TRUE) or synchronous (FALSE) execution.

--> ioCompletion ProcPtr A pointer to a completion routine.
<-- ioResult OSErr The result code of the function.
--> ioVRefNum Integer A working directory reference number.

DESCRIPTION
The PBCloseWD function releases the working directory whose working directory reference number is specified in ioVRefNum.

Note
If you specify a volume reference number in the ioVRefNum field, PBCloseWD does nothing.
