- 41 Alias Mgr Q&As.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: Alias Mgr Q&As - This Technical Note contains a collection of Q&As
- KEY: Alias Mgr Q&As.sit KBytes: 5120
- DESC: relating to a specific topic—questions you’ve sent the Developer
- DESC: Support Center (DSC) along with answers from the DSC engineers.
- DESC: While DSC engineers have checked the Q&A content for accuracy, the
- DESC: Q&A Technical Notes don’t have the editing and organization of
- DESC: other Technical Notes. The Q&A function is to get new technical
- DESC: information and updates to you quickly, saving the polish for when
- DESC: the information migrates into reference manuals.

- 39 Blessed Folder.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: Blessed Folder - This Technical Note describes how to determine
- KEY: Blessed Folder.sit KBytes: 6144
- DESC: which folder on an HFS volume is the blessed folder, that is, the
- DESC: folder that contains both the System file and the Finder. Changes
- DESC: since January 1986, The information about how to find the "Blessed
- DESC: Folder" has been deleted from this technical note. The FindFolder
- DESC: function can now be used to find the "Blessed Folder" and is
- DESC: documented in Inside Macintosh Volume VI, pages 9-42 to 9-44. This
- DESC: note now includes information about how to bless a folder to the
- DESC: new system folder.

- 38 Caching.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: Caching - This technical note describes disk and File System caching
- KEY: Caching.sit KBytes: 7168
- DESC: on the Macintosh, with particular emphasis on the high-level File
- DESC: System cache. Of the three caches used for file I/O, this is the one
- DESC: which could have the most impact on your program.

- DESC: File Sharing - This Note describes modifications to the existing
- KEY: File Sharing .sit KBytes: 10240
- DESC: File Manager routines, PBGetCatInfo, PBHGetDirAccess,
- DESC: PBHSetDirAccess, PBHSetFLock and PBHRstFLock, when used on volumes
- DESC: prepared by Macintosh System 7 File Sharing. There are several
- DESC: differences between System 7 File Sharing and AppleShare 2.0.1.
- DESC: This Note describes what those differences mean when calling
- DESC: PBGetCatInfo, PBHGetDirAccess, PBHSetDirAccess, PBHSetFLock and
- DESC: PBHRstFLock on local volumes that return bHasPersonal
- DESC: AccessPrivileges to PBHGetVolParms.

- DESC: Hard Disk Medic - The death of a hard disk with megabytes worth of
- KEY: Hard Disk Medic.sit KBytes: 18432
- DESC: data can be exceedingly traumatic. This technical note will describe
- DESC: techniques for recovering a hard disk and the data that is on it.
- DESC: The discussion will also include some tips on how to avoid problems.

- 25 HFS Elucidations.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: HFS Elucidations - This technical note will describe a few problems
- KEY: HFS Elucidations.sit KBytes: 9216
- DESC: that can occur while using HFS. It will also describe ways to avoid
- DESC: these problems.
- DESC:
- 24 HFS Ruminations.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: HFS Ruminations - This technical note contains some thoughts
- KEY: HFS Ruminations.sit KBytes: 10240
- DESC: concerning HFS.

- 23 HFS Tidbits.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: HFS Tidbits - This Technical Note describes two poorly documented

- 22 ioNamePtr.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: ioNamePtr - It is very important to set ioNamePtr when making PB
- KEY: ioNamePtr.sit KBytes: 4096
- DESC: calls, even if you don’t want those calls to return a name.
- DESC: Whenever Inside Macintosh indicates that ioNamePtr is either
- DESC: required for input or returns something, you must set ioNamePtr to
- DESC: either nil (if you aren’t using a name) or to point to storage for
- DESC: a Str255. If you don’t explicitly set ioNamePtr, strange and
- DESC: unusual crashes may occur, depending on the machine/configuration
- DESC: your code is run on.

- 21 ioPosOffset.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: ioPosOffset - The Device Manager chapter of Inside Macintosh Volume
- KEY: ioPosOffset.sit KBytes: 4096
- DESC: II says that ioPosOffset is passed to and returned by Read and Write
- DESC: calls. It also says that “After the read [or write] is completed,
- DESC: the position is returned in ioPosOffset…” Actually, ioPosOffset is
- DESC: not changed by either call. Also note that device drivers should
- DESC: only look at the dCtlPosition field of the DCE, and should not look
- DESC: directly at the ioPosOffset field of the parameter block. The Device
- DESC: Manager sets up dCtlPosition for the driver, taking into account
- DESC: both the ioPosMode and the ioPosOffset.

- 14 PBHSetVol.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: PBHSetVol - This note explains PBHSetVol, and why its use is not
- KEY: PBHSetVol.sit KBytes: 5120
- DESC: recommended. PBHSetVol, like SetVol and PBSetVol, allows you to set
- DESC: the current default volume and directory to be used with subsequent
- DESC: File Manager calls. Unlike SetVol and PBSetVol, though, PBHSetVol
- DESC: lets you specify the volume and the directory separately, using the
- DESC: ioVRefNum and ioWDDirID fields.

- 9 Spare A Block.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: Spare A Block - This Technical Note discusses a new feature of the

- 5 Tags.sit 0 B AMUG BBS in a Box 10-29-1992
- DESC: Tags - Apple has decided to eliminate support for file-system tags
- KEY: Tags.sit KBytes: 5120
- DESC: on its future products; this technical note explains this decision.
- DESC: Some of Apple’s disk products (and some third-party products) have
- DESC: the ability to store 532 bytes per sector, instead of the normal
- DESC: 512. Twelve of the extra bytes are used to store redundant file
- DESC: system information, known as “tags”, to be used by a scavenging
- DESC: utility to reconstruct damaged disks.
