HSetVol
You can use theHSetVol
function to set both the default volume and the default directory.
FUNCTION HSetVol (volName: StringPtr; vRefNum: Integer; dirID: LongInt): OSErr;
volName
- A pointer to the name of a mounted volume or the partial pathname
of a directory.vRefNum
- A volume reference number or a working directory reference number.
dirID
- A directory ID.
DESCRIPTION
TheHSetVol
function lets you specify the default directory by volume reference number, by directory ID, or by a combination of working directory reference number
and partial pathname (beginning from that working directory).
- WARNING
- Use of the
HSetVol
function is discouraged if your application may execute in system software versions prior to version 7.0. Because the specified directory might not itself be a working directory,HSetVol
records the default volume and directory separately, using the volume reference number of the volume and the actual directory ID of the specified directory. Subsequent calls toGetVol
(orPBGetVol
) return only the volume reference number, which will cause that volume's root directory (rather than the default directory, as expected) to be accessed.- Note
- Both the default volume and the default directory are used in calls made with no volume name, a volume reference number of 0, and a directory ID of 0.
