|
||
* The PBHGetVInfo function returns information about the specified
|
||
* volume. If the value of ioVolIndex is positive, the File Manager
|
||
* attempts to use it to find the volume; for instance, if the
|
||
* value of ioVolIndex is 2, the File Manager attempts to access
|
||
* the second mounted volume in the VCB queue. If the value of
|
||
* ioVolIndex is negative, the File Manager uses ioNamePtr and
|
||
* ioVRefNum in the standard way to determine the volume. If the
|
||
* value of ioVolIndex is 0, the File Manager attempts to access
|
||
* the volume by using ioVRefNum only. The volume reference number
|
||
* is returned in ioVRefNum, and the volume name is returned in
|
||
* the buffer whose address you passed in ioNamePtr. You should
|
||
* pass a pointer to a Str31 value if you want that name returned.
|
||
* If you pass NIL in the ioNamePtr field, no volume name is
|
||
* returned.
|
||
*
|
||
* If you pass a working directory reference number in ioVRefNum
|
||
* (or if the default directory is a subdirectory), the number
|
||
* of files and directories in the specified directory (the
|
||
* directory’s valence) is returned in ioVNmFls.
|
||
*
|
||
* You can read the ioVDrvInfo and ioVDRefNum fields to determine
|
||
* whether the specified volume is online, offline, or ejected.
|
||
* For online volumes, ioVDrvInfo contains the drive number of
|
||
* the drive containing the specified volume and hence is always
|
||
* greater than 0. If the value returned in ioVDrvInfo is 0, the
|
||
* volume is either offline or ejected. You can determine whether
|
||
* the volume is offline or ejected by inspecting the value of
|
||
* the ioVDRefNum field. For online volumes, ioVDRefNum contains
|
||
* a driver reference number; these numbers are always less than
|
||
* 0. If the volume is not online, the value of ioVDRefNum is
|
||
* either the negative of the drive number (if the volume is
|
||
* offline) or the drive number itself (if the volume is ejected).
|
||
*
|
||
*
|
||
* You can get information about all the online volumes by making
|
||
* repeated calls to PBHGetVInfo, starting with the value of
|
||
* ioVolIndex set to 1 and incrementing that value until PBHGetVInfo
|
||
* returns nsvErr.
