The File Manager chapter of Inside Macintosh volume IV is not very specific in describing how to use ioFDirIndex when calling PBGetCatInfo. It correctly says that ioFDirIndex should be positive if you are making indexed calls to PBGetCatInfo (analogous to making indexed calls to PBGetVInfo as described in Technical Note #24). Name = PBClose the Barn Door.sit Path = AMUG CD:Files:MacTechNotes:Devices:PBClose the Barn Door.sit Size: 5K Date:10/29/92 Version: Description: PBClose the Barn Door - This Technical Note discusses the need for Macintosh device drivers to implement _PBClose. You may get the idea when implementing device drivers that _PBClose is superfluous. After all, if you have a resident driver for a NuBus™ video board, the only time your driver is not needed is if the operating system is going away. It might seem that nothing important can happen after the operating system goes away, so why bother with _PBClose? Well, it turns out a lot can happen, and this Note tells you why it is important to implement a Close (_PBClose) routine.

Name = Object Pascal.sit Path = AMUG CD:Files:MacTechNotes:Platforms & Tools:Object Pascal.sit Size: 5K Date:10/29/92 Version: Description: Object Pascal - Object Pascal must have a CODE segment named %_MethTables in order to access object methods. In MacApp this is taken care of “behind the scenes” so you don’t have to worry about it . However, if you are doing a straight Object Pascal program, you must make sure that %_MethTables is around when you need it. If it’s unloaded when you call a method, your Macintosh will begin executing wild noncode and die a gruesome and horrible death. Name = Number of Resources.sit Path = AMUG CD:Files:MacTechNotes:Toolbox:Number of Resources.sit Size: 4K Date:10/29/92 Version: Description: Number of Resources - This note describes the limitation of the number of resources in a single resource file.

Name = MoveHHi and SetResPurge.sit Path = AMUG CD:Files:MacTechNotes:Memory:MoveHHi and SetResPurge.sit Size: 4K Date:10/29/92 Version: Description: MoveHHi and SetResPurge - SetResPurge(TRUE) is called to make the Memory Manager call the Resource Manager before purging a block specified by a handle. If the handle is a handle to a resource, and its resChanged bit is set, the resource data will be written out (using WriteResource). When MoveHHi is called, even though the handle’s block is not actually being purged, the resource data specified by the handle will be written out. An application can prevent this by calling SetResPurge(FALSE) before calling MoveHHi (and then calling SetResPurge(TRUE) after the MoveHHi call).

Problems with Communication Between HFS and C. Frequently, developers want to use both Macintosh file I/O and C file I/O. Developers who do this must keep in mind that they are combining two distinct file representations (the Macintosh and ANSI C). The only limitation on mixing HFS and C I/O functions is that they cannot be mixed on the same open file. There are three reasons why this cannot be done.

Because of this, PrError will return (and PrintErr will contain) abortErr. Name = Lock, Unlock the Range.sit Path = AMUG CD:Files:MacTechNotes:Files:Lock, Unlock the Range.sit Size: 7K Date:10/29/92 Version: Description: Lock, Unlock the Range - This Technical Note discusses the _PBLockRange and _PBUnlockRange routines; how they act on local and shared volumes and why you should not set the ioPosMode field to fsFromLEOF in the parameter block for those routines when accessing a file on an AppleShare volume. Changes since April 1988. Added information on how _PBLockRange and _PBUnlockRange really work.

Name = LaserWriter ROM Bugs.sit Path = AMUG CD:Files:MacTechNotes:Imaging:Printing:LaserWriter ROM Bugs.sit Size: 6K Date:10/29/92 Version: Description: LaserWriter ROM Bugs - These are LaserWriter bugs that your users may encounter when printing from any Macintosh application. These are for your information; you cannot code around them. The bugs described here occur in the 1.0 and 2.0 LaserWriter ROMs. Name = Large Screen Displays.sit Path = AMUG CD:Files:MacTechNotes:Overview:Large Screen Displays.sit Size: 5K Date:10/29/92 Version: Description: Large Screen Displays - A number of third-party developers have announced large-screen display peripherals for Macintosh. One of them, Radius Inc., has issued a set of guidelines for developers who wish to remain compatible with their Radius FPD; unfortunately, one of their recommendations can cause system crashes. This note suggests a more correct approach. Name = LDEF Madness.sit Path = AMUG CD:Files:MacTechNotes:Toolbox:LDEF Madness.sit Size: 6K Date:10/29/92 Version: Description: LDEF Madness - This Technical Note uncovers a problem with writing Pascal list definition procedures and two (yes, count ’em, two) different methods to work around it. Name = LAP Q&As.sit Path = AMUG CD:Files:MacTechNotes:Networking:LAP Q&As.sit Size: 9K Date:10/29/92 Version: Description: LAP Q&As - This Technical Note contains a collection of Q&As relating to a specific topic—questions you’ve sent the Developer Support Center (DSC) along with answers from the DSC engineers.

Name = KillNBP.sit Path = AMUG CD:Files:MacTechNotes:Networking:KillNBP.sit Size: 4K Date:10/29/92 Version: Description: KillNBP - This technical note clears up some confusion regarding the Name Binding Protocol KillNBP function. The description of the PKillNBP function on page 519 of Inside Macintosh Volume V is somewhat confusing. The data type of the parameter thePBptr is incorrectly given as ATPPBPtr and the pointer to the queue element from the NBP call to be aborted is incorrectly given as being passed in aKillQEl. Name = Keybd Resource Q&As.sit Path = AMUG CD:Files:MacTechNotes:Text:Keybd Resource Q&As.sit Size: 8K Date:10/29/92 Version: Description: Keybd Resource Q&As - This Technical Note contains a collection of Q&As relating to a specific topic—questions you’ve sent the Developer Support Center (DSC) along with answers from the DSC engineers.

Name = Key Mapping.sit Path = AMUG CD:Files:MacTechNotes:Toolbox:Key Mapping.sit Size: 11K Date:10/29/92 Version: Description: Key Mapping - This Technical Note describes the Macintosh family key code mapping scheme when running System file 4.1 and later. This Note also provides a “safe” method for remapping keyboards. Changes since October 1990. Added a section on how 'KMAP' resources are matched to specific ADB keyboard types and a section on the original Macintosh and Macintosh Plus keyboards. Name = Joy of 32-Bit Clean.sit Path = AMUG CD:Files:MacTechNotes:Overview:Joy of 32-Bit Clean.sit Size: 9K Date:10/29/92 Version: Description: Joy of 32-Bit Clean - What to do (and what not to do) to make your programs run under A/UX and future versions of the Macintosh System Software. Changes since October 1988: Added information on writing 32-bit clean CDEFs, and updated A/UX information to reflect the capabilities of A/UX 1.1. Name = ioPosOffset.sit Path = AMUG CD:Files:MacTechNotes:Files:ioPosOffset.sit Size: 4K Date:10/29/92 Version: Description: ioPosOffset - The Device Manager chapter of Inside Macintosh Volume II says that ioPosOffset is passed to and returned by Read and Write calls. It also says that “After the read [or write] is completed, the position is returned in ioPosOffset…” Actually, ioPosOffset is not changed by either call. Also note that device drivers should only look at the dCtlPosition field of the DCE, and should not look directly at the ioPosOffset field of the parameter block. The Device Manager sets up dCtlPosition for the driver, taking into account both the ioPosMode and the ioPosOffset. Name = ioNamePtr.sit Path = AMUG CD:Files:MacTechNotes:Files:ioNamePtr.sit Size: 4K Date:10/29/92 Version: Description: ioNamePtr - It is very important to set ioNamePtr when making PB calls, even if you don’t want those calls to return a name. Whenever Inside Macintosh indicates that ioNamePtr is either required for input or returns something, you must set ioNamePtr to either nil (if you aren’t using a name) or to point to storage for a Str255. If you don’t explicitly set ioNamePtr, strange and unusual crashes may occur, depending on the machine/configuration your code is run on. Name = Int'l Resource Q&As.sit Path = AMUG CD:Files:MacTechNotes:Text:Int'l Resource Q&As.sit Size: 10K Date:10/29/92 Version: Description: Int'l Resource Q&A - This Technical Note contains a collection of Q&As relating to a specific topic—questions you’ve sent the Developer Support Center (DSC) along with answers from the DSC engineers. While DSC engineers have checked the Q&A content for accuracy, the Q&A Technical Notes don’t have the editing and organization of other Technical Notes.

Name = Inside Object Pascal.sit Path = AMUG CD:Files:MacTechNotes:Platforms & Tools:Inside Object Pascal.sit Size: 5K Date:10/29/92 Version: Description: Inside Object Pascal - This Technical Note briefly explains why Object Pascal and MacApp should only be used to write applications and MPW tools. Although Pascal can be used to write desk accessories, drivers, XCMDs and other types of stand–alone code, and Object Pascal is an extension of Pascal, Object Pascal cannot be used to write anything other than an application. This limitation is due to the fact that Object Pascal method dispatching relies on a valid A5 pointing to a jump table. Because MacApp is written in Object Pascal, this limitation applies to it as well. Name = Image Writer IIMotio.sit Path = AMUG CD:Files:MacTechNotes:Imaging:Printing:Image Writer IIMotio.sit Size: 5K Date:10/29/92 Version: Description: Image Writer II Motion - The purpose of this technical note is to answer the many questions asked about why the paper moves the way it does on the ImageWriter II.

Name = Identifying Features.sit Path = AMUG CD:Files:MacTechNotes:Overview:Identifying Features.sit Size: 7K Date:10/29/92 Version: Description: Identifying Features - This technical note explains how to check at run time to see if specific functionality, such as the “new” TextEdit, is present. Applications should strive to be compatible across all Macintoshes, but there are times when an application must have knowledge about the machine that it is running on. The new trap, SysEnvirons, will give an application most of the information that it requires (what hardware, what version of system software…). Name = Icon Drawing in 7.sit Path = AMUG CD:Files:MacTechNotes:Imaging:Graphics:Icon Drawing in 7.sit Size: 15K Date:10/29/92 Version: Description: Icon Drawing in 7 - This Technical Note describes how to utilize the built-in System 7 icon drawing utility. Use this information to better conform to the System 7 visual human interface. Changes since May 1992. In this Note, we replaced the C and Pascal interface files and corrected the related text. So much text was tweaked that change bars are used only on code changes. Name = ISO 9660 CD ROM Format.sit Path = AMUG CD:Files:MacTechNotes:Files:ISO 9660 CD ROM Format.sit Size: 5K Date:10/29/92 Version: Description: ISO 9660 CD ROM Format - What’s Wrong with my High Sierra Disc? Generally, if a Macintosh has problems with a High Sierra disc, it’s because the disc in question doesn’t really conform to the High Sierra specification. Name = IOP Diffs Under A/UX.sit Path = AMUG CD:Files:MacTechNotes:Platforms & Tools:IOP Diffs Under A/UX.sit Size: 6K Date:10/29/92 Version: Description: IOP Diffs Under A/UX - This Technical Note discusses use of the Macintosh IIfx IOP-based serial driver under A/UX, especially under certain error conditions which cause it to perform differently than documented in termio(7). (The SCC driver, used on non-IOP machines, conforms to termio(7) in all cases.) References to “the driver” herein refer to the IOP-based serial driver, seriop.c. Name = HyperCard and You.sit Path = AMUG CD:Files:MacTechNotes:Platforms & Tools:HyperCard and You.sit Size: 14K Date:10/29/92 Version: Description: HyperCard and You - This Technical Note describes some HyperCard anomalies with which developers should be familiar when developing stackware, and it documents differences between HyperCard versions where appropriate. Changes since November 1987. Updated material with regard to HyperCard 2.0 and condensing or obsoleting information on bugs which have been addressed. Name = Help Mgr Q&As.sit Path = AMUG CD:Files:MacTechNotes:Toolbox:Help Mgr Q&As.sit Size: 17K Date:10/29/92 Version: Description: Help Mgr Q&As - This Technical Note contains a collection of Q&As relating to a specific topic—questions you’ve sent the Developer Support Center (DSC) along with answers from the DSC engineers.

Name = Hard Disk Hacking.sit Path = AMUG CD:Files:MacTechNotes:Devices:Hard Disk Hacking.sit Size: 5K Date:10/29/92 Version: Description: Hard Disk Hacking - For those of a technical bent with some extra time, you can build your own hard disk system from a cheap SCSI drive and a driver that you write. This is not a project for those short on time, so beware. Name = Handles vs. Pointers.sit Path = AMUG CD:Files:MacTechNotes:Memory:Handles vs. Pointers.sit Size: 5K Date:10/29/92 Version: Description: Handles vs. Pointers - A handle is a handle and a pointer is a pointer. Applications should avoid embedding non-relocatable objects (that the system assumes will never move) in handles. In order to avoid fragmentation, some applications embed pointers (non-relocatable memory manager objects) in handles, so that the handles can be moved around as needed. This can cause several problems, especially with the Macintosh II, and should be avoided. Name = HFS Tidbits.sit Path = AMUG CD:Files:MacTechNotes:Files:HFS Tidbits.sit Size: 5K Date:10/29/92 Version: Description: HFS Tidbits - This Technical Note describes two poorly documented features of the File Manager. Name = HFS Ruminations.sit Path = AMUG CD:Files:MacTechNotes:Files:HFS Ruminations.sit Size: 10K Date:10/29/92 Version: Description: HFS Ruminations - This technical note contains some thoughts concerning HFS.

It will also describe ways to avoid these problems. Name = HFS Comaptibility.sit Path = AMUG CD:Files:MacTechNotes:Files:HFS Comaptibility.sit Size: 7K Date:10/29/92 Version: Description: HFS Comaptibility - This technical note tells you how to make sure that your applications run under the Hierarchical File System (HFS). The Hierarchical File System (HFS) provides fast, efficient management of larger volumes than the original Macintosh File System (MFS). Since HFS is hierarchical, HFS folders have a meaning different from MFS folders. In MFS, a folder has only graphical significance—it is only used by the Finder as a means of visually grouping files. The MFS directory structure is actually flat (all files are at the ‘root’ level). Under HFS, a folder is a directory that can contain files and other directories. Name = Getting thru CUSToms.sit Path = AMUG CD:Files:MacTechNotes:Platforms & Tools:Getting thru CUSToms.sit Size: 15K Date:10/29/92 Version: Description: Getting thru CUSToms - This technical note provides a way for developers to allow sophisticated users to add code to an off-the-shelf application. Using this scheme, the user can easily install the code module; the application has to know how to call it and, optionally, be able to respond to a set of predefined calls from the custom package. Name = Getting a Full Pathname.sit Path = AMUG CD:Files:MacTechNotes:Files:Getting a Full Pathname.sit Size: 8K Date:10/29/92 Version: Description: Getting a Full Pathname - This Technical Note describes how to generate a full pathname, given either a Working Directory ID or a real vRefNum and a DirID. By using the techniques shown in this Note, you can find the full pathname from information such as that returned by Standard File. Changes since June 89. Added a note on how to check for A/UX. Fixed bug in C version: BlockMove() parameters were reversed in pStrcpy(); added range checking to pStrCat(); changed references from “longint” to “long”. Fixed bug in Pascal and C versions. Changed fsRtDir to fsRtdirID and made references to gHaveAUX consistent. Name = GetNextEvent & Blinking App.sit Path = AMUG CD:Files:MacTechNotes:Toolbox:GetNextEvent & Blinking App.sit Size: 5K Date:10/29/92 Version: Description: GetNextEvent & Blinking App - Wherein arcane mysteries are unraveled so you can make the Alarm Clock (or a similar desk accessory) blink the Apple menu at the appointed second. Also, why GetNextEvent is a good thing. Name = GDevice Mgr Q&As.sit Path = AMUG CD:Files:MacTechNotes:Devices:GDevice Mgr Q&As.sit Size: 15K Date:10/29/92 Version: Description: GDevice Mgr Q&As - This Technical Note contains a collection of Q&As relating to a specific topic—questions you’ve sent the Developer Support Center (DSC) along with answers from the DSC engineers.

Changes since March 1992. Corrected the Vulcan-like “THPring” typo to correctly read “THPrint,” and changed a comment in the code to mean what I originally meant. Name = Forcing Floppy Size.sit Path = AMUG CD:Files:MacTechNotes:Devices:Forcing Floppy Size.sit Size: 5K Date:10/29/92 Version: Description: Forcing Floppy Size - This document explains how to initialize a disk as either single- or double- sided. It only applies to 800K drives, of course. You can call the disk driver to initialize a disk and determine programmatically whether it should be initialized as single- (MFS) or double- (HFS) sided. All you have to do is call the .Sony driver directly to do the formatting then the Disk Initialization Package to write the directory information. Name = Fonts and the Script Mgr.sit Path = AMUG CD:Files:MacTechNotes:Text:Fonts and the Script Mgr.sit Size: 9K Date:10/29/92 Version: Description: Fonts and the Script Mgr - This Technical Note describes how the Script Manager uses the font family ID to determine a script code. Name = Font Names.sit Path = AMUG CD:Files:MacTechNotes:Imaging:Fonts:Font Names.sit Size: 8K Date:10/29/92 Version: Description: Font Names - This note recommends the use of font names rather than font numbers. The Font Manager chapter of Inside Macintosh Volume IV claims that font family numbers 0 through 127 are reserved for use by Apple, and numbers 128 through 255 are assigned by Apple for fonts created by software developers. This is no longer true. Developer Technical Support does not assign font family numbers. You should only use font numbers to reference the system font (font 0) and application default font (font 1). All other fonts should be identified by name. The Font/DA Mover will renumber a font when moving it into a file containing a conflicting font family. Name = Font Mgr Q&As.sit Path = AMUG CD:Files:MacTechNotes:Text:Font Mgr Q&As.sit Size: 15K Date:10/29/92 Version: Description: Font Mgr Q&As - This Technical Note contains a collection of Q&As relating to a specific topic—questions you’ve sent the Developer Support Center (DSC) along with answers from the DSC engineers.

Name = Font File Icons.sit Path = AMUG CD:Files:MacTechNotes:Imaging:Fonts:Font File Icons.sit Size: 5K Date:10/29/92 Version: Description: Font File Icons - This Technical Note discusses why you should not link directly from your font files to the font icons provided by LaserWriter driver 5.2 and later. Changes since December 1988. Added some useful tips and described the method required to bundle an icon to your font file. Name = Font Family Numbers.sit Path = AMUG CD:Files:MacTechNotes:Imaging:Fonts:Font Family Numbers.sit Size: 9K Date:10/29/92 Version: Description: Font Family Numbers - This Technical Note discusses the range of numbers available for identifying font families, how they are allocated among script systems, and what numbers should be used for fonts that were designed to be used as a tool in an application. Changes since August 1990. Apple Computer no longer registers font family ID numbers; this note has been altered to reflect the change in policy. Also, the relationship of outline fonts to font families is discussed briefly. Name = Fond of FONDs.sit Path = AMUG CD:Files:MacTechNotes:Text:Fond of FONDs.sit Size: 25K Date:10/29/92 Version: Description: Fond of FONDs - This Technical Note takes the place of Tech Note #26, “Character vs. String Operations in QuickDraw” by Bryan Stearns (March 1988), which pointed out the possible differences between the results of a StringWidth call and successive calls to CharWidth. This Note updates and brings into a broader context the issues related to text measuring. It also provides additional documentation on font family resources ('FOND's), and addresses various other frequently asked questions related to the Font Manager.

Name = Available Volumes.sit Path = AMUG CD:Files:MacTechNotes:Files:Available Volumes.sit Size: 5K Date:10/29/92 Version: Description: Available Volumes - Standard File lets the user select one file from any available volume; it is sometimes necessary for an application to find which volumes are present. This technical note gives the proper method of accomplishing this. There is a little-noticed feature of the low-level file manager call PBHGetVInfo which allows specification of a “volume index” to select the volume. Name = Author Index.sit Path = AMUG CD:Files:MacTechNotes: Indexes:Author Index.sit Size: 9K Date:10/29/92 Version: Description: Author Index - This index lists each author and the Technical Notes they are responsible for.

Name = AppleShare and Old Finder.sit Path = AMUG CD:Files:MacTechNotes:Networking:AppleShare and Old Finder.sit Size: 4K Date:10/29/92 Version: Description: AppleShare and Old Finder - A rumor has been spread that if you use a pre-AppleShare Finder on a workstation to access AppleShare volumes, you can bypass AppleShare’s “access privilege” mechanisms. This is not true. Access controls are enforced by the server, not by the Finder. If you use an older Finder, you are still prevented (by the server) from gaining access to protected files and folders; however, you will not get the proper user-interface feedback that you would if you were using the correct Finder. Name = AppleShareable Applications.sit Path = AMUG CD:Files:MacTechNotes:Networking:AppleShareable Applications.sit Size: 6K Date:10/29/92 Version: Description: AppleShareable Applications - Normally, applications on an AppleShare server volume cannot be executed by more than one user at a time.

Name = AppleShare Limits.sit Path = AMUG CD:Files:MacTechNotes:Networking:AppleShare Limits.sit Size: 5K Date:10/29/92 Version: Description: AppleShare Limits - This Technical Note describes some machine-dependent limits of current versions of AppleShare and AppleShare servers. The following chart lists some current AppleShare limits which are based upon the chosen server platform and memory configuration. The limits which otherwise might be present on a workstation are still in effect and are not affected by the workstation being logged into an AppleShare server. These limits will change in the future. Name = AppleShare Foreground Apps.sit Path = AMUG CD:Files:MacTechNotes:Networking:AppleShare Foreground Apps.sit Size: 5K Date:10/29/92 Version: Description: AppleShare Foreground Apps - This technical note outlines the requirements and restrictions of an AppleShare foreground application. This information pertains to AppleShare versions 1.1 and newer. An AppleShare server requires a dedicated Macintosh. The server, however, is implemented as an interrupt-driven application that runs in the system heap of the server machine. This allows the running of a concurrent or foreground application that will live in the application heap of the server machine. An example of a foreground application is LaserShare, the LaserWriter spooler available from Apple. Name = AppleEvents Send to Self.sit Path = AMUG CD:Files:MacTechNotes:Interapplication Comm.:AppleEvents Send to Self.sit Size: 8K Date:10/29/92 Version: Description: AppleEvents Send to Self - If an application suspends handling of an Apple event which it sent to itself, the Apple Event Manager will return errAETimeout as the result of the AESend call. The event was still sent correctly, however, and the answer (if any) should appear later in the reply descriptor. However, a problem in system software versions 7.0 and 7.0.1 prevents applications from getting the reply data.

Because this can happen, you can’t be guaranteed that register A5 will be correct. If your grow zone function depends on A5, you should save register A5, load A5 from the low-memory global CurrentA5 (a long word at $904), and restore the caller’s A5 before you exit. Name = A5 and Patching traps.sit Path = AMUG CD:Files:MacTechNotes:Overview:A5 and Patching traps.sit Size: 5K Date:10/29/92 Version: Description: A5 and Patching traps - Future software may allow desk accessories to have their own globals by changing register A5 when the accessory is entered and exited. This can cause problems for applications that patch traps without following certain rules.
