 Sept 93 Late-Breaking Q&A - September 1993 Late-Breaking Q&As. This is a
new way of getting special Q&As to you before they’ve been completely
reviewed, copy-edited, and added to the Q&A Tech Notes. The content is
preliminary; it’s been verified by each author, but you might notice
changes when you see the final version in a Q&A Tech Note. Examples of the
questions - What do I have to do to make my CD-ROM driver work with Foreign
File Access? Is Foreign File Access licensable from Apple? My SCSI driver
sometimes hangs and I have to reset the bus. Am I making a common mistake?
What’s the Macintosh built-in analog sound input port signal specification?
Includes many more questions.

 Description:
 SCSI Termination - The introduction of the Apple Workgroup Server 95 has
led to questions with regard to the SCSI termination requirements for the
internal Processor Direct Slot Card and the SCSI busses that it supports.
The internal and external SCSI buses on the AWS95 are two separate
electrical buses that are logically treated as one via software. This means
external cabling and termination issues do not affect the internal bus and
vice-versa. Both buses are terminated at the main board. Find out more by
reading this Technical note.

 10+ Commandments - The world of Macintosh is changing rapidly. With a
plethora of new Macintosh CPUs and the prospect of even stranger, non-68K
CPUs on the horizon, how’s a programmer supposed to keep up? Maybe it’s
time to review some basic tenets of Macintosh programming and point out
some future pitfalls. Not only is it important that Apple evolve new
hardware; Apple must evolve the operating system as well. The issues
discussed here affect the ability of Apple to transform the Macintosh
Operating System into a modern operating system. As you write new code, or
review old code, be aware of these issues.

 Description:
 Position ind PS - This technical note describes a method for inserting
position-independent PostScript into QuickDraw pictures. There is a problem
with pictures that contain PostScript code. Sometimes the PostScript code
that is inserted into the picture is dependent on the position of the
picture on the page. The problem arises when these pictures are cut or
copied from their original position, and pasted into another position or
even into another document. The PostScript code will not know the new
location of the picture, and will not execute correctly.

 Pictures and Clip Regions - This note describes a problem that affects
creation of QuickDraw pictures. When a GrafPort is created, the fields in
the GrafPort are given default values; one of these is the clip region,
which is set to the rectangle (–32767, –32767, 32767, 32767). If you create
a picture, then call DrawPicture with a destination rectangle that is not
the same size as the picFrame without ever changing the default clip
region, nothing will be drawn.

 Description:
 PictComments Real Deal - Changes since March 1988:  This Note (formerly
titled “Optimizing for the LaserWriter—PicComments”) describes the picture
comments defined and interpreted by the Apple printer drivers. Most of the
picture comments are specific to PostScript, but we renamed the Note to
emphasize that LaserWriter printers are not necessarily PostScript devices,
and that QuickDraw printer drivers may implement their own picture comment
handling. This Note has been completely rewritten and incorporates all
additional insights gained during the last few years.

 Description:
 PBGetCatInfo&ioFDirIndex - This technical note describes how to set
ioFDirIndex for PBGetCatInfo. 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).

 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.

 Path =  Trilogy III:Files:MacTechNotes:Platforms & Tools:Object Pascal
 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.

 Description:
 Nulls in Filenames - Some applications (loosely speaking so as to include
Desk Accessories, INITs, and what-have-you) generate or rename special
files on the fly so that they are not explicitly named by the user via
SFPutFile. Since the Macintosh file system is very liberal about filenames
and only excludes colons from the list of acceptable characters, this can
lead to some difficulties, both for the end user and for writers of other
programs which may see these files.

 Description:
 NuBus Interrupt Latency - This Technical Note discusses NuBus™ interrupt
latency, and why, contrary to popular belief, the Macintosh is not a
real-time machine. Changes since December 1988. Changed sample code to
defer cursor rendering to a deferred task rather than a “pseudo-VBL” task.
The Macintosh is not a real-time machine.  The Macintosh does not support
DMA. There are many variables in the Macintosh that make it impossible to
deterministically figure out exactly when things are going to happen.
Despite these facts, there are those who must push the envelope. For these
courageous adventurers, we provide the following information in the hope
that it speeds your journey.

 Description:
 NuBus Block Transfers - This Technical Note describes the sResource entries
needed in a declaration ROM to inform NuBus™ masters when a board is
capable of receiving or sending block transfers. In addition to normal long
word transfers, the NuBus specification defines a number of block transfer
transactions. In block mode transfers, the system arbitrates for the bus a
single time and then performs a group of consecutive long word transfers
before releasing the bus. The reduction in bus arbitration time can result
in considerable gains in performance.

 Path =  Trilogy III:Files:MacTechNotes:Memory:MoveHHi and SetResPurge
 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).

 Description:
 Mixing HFS and C I/O - This Technical Note discusses the problem of mixing
calls to the Macintosh file system with calls to MPW C library file I/O
routines. 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.

 Name  =  ioPosOffset
 Path =  Trilogy III:Files:MacTechNotes:Files:ioPosOffset
 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
 Path =  Trilogy III:Files:MacTechNotes:Files:ioNamePtr
 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.

 Path =  Trilogy III:Files:MacTechNotes:Platforms & Tools:Inside Object Pascal
 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.

 Path =  Trilogy III:Files:MacTechNotes:Memory:Handles vs. Pointers
 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.

 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.

 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.

 Don’t Call ADBReInit in sys - Because of a bug (which causes auto-repeat)
in the ROM version of the Macintosh SE keyboard driver, a patch was placed
in System 4.1. If ADBReInit is called, the ROM version of the keyboard
driver will be reloaded, and the RAM version of the driver with the patches
will not be used. Therefore, it is recommended that ADBReInit not be called
on the Macintosh SE until the problem is fixed. (There is no need to call
