 Description:
 Printing Loop Cares - A Printing Loop that Cares - This Technical Note
discusses opening and closing the Printing Manager with calls to _PrOpen
and _PrClose as well as how to handle errors at print time. Changes since
October 1990 - Added code in both versions to handle printing documents
larger than 128 pages. Introduction - At one time, Apple recommended that
developers call _PrOpen at the beginning of their application and _PrClose
at the end, before returning to the Finder. This recommendation was in the
ancient past when an application only had to deal with a single printer
driver. As more printer drivers became available, it became important for
an application to consider the presence of other applications.

 ARA GetPortGlobal - This Technical Note documents the Remote Access Manager
(RAM) GetUserPortGlobalsPtr call. In order to make the RAM Status call on a
machine that is setup to answer calls, you must first make the
GetUserPortGlobalsPtr call to retrieve a pointer to the globals for the
user port. The Apple Remote Access (ARA) 1.0 client software supports
dial-out and answering capabilities through a single port called the “user”
port (the modem or printer port on your Mac). This means that when you
setup your machine to answer calls, you can answer only one call at a time
on the user port. However, the underlying ARA architecture was designed so
that in the future multiple ports may be supported...

 ADBReInit in sys 4.2 - 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
ADBReInit.) This problem will not occur with the Macintosh II ROM version
of the keyboard driver.

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.

 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.

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

 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.

 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.

 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.

 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).

 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.

represents Extended values in 96 bits (instead of 80, as with software
SANE), and compatibility issues when using non-SANE system calls that
expect 80-bit Extended values. Changes since June 1990. Extended the
warning about explicitly checking for the presence of an FPU if an
application uses floating-point instructions to include the possibility of
FPU-less MC68040 products and also raised the issue of extended values

 Description:
 Low-Level Printing - When you use the low-level printer driver to print,
you don’t get the benefits of the error checking that is done when you use
the high-level Printing Manager. So, if the user prints to an AppleTalk
ImageWriter (including an AppleTalk ImageWriter LQ) that is busy printing
another job, the driver doesn’t know whether the printer is busy, offline,
or disconnected.  Because of this, PrError will return (and PrintErr will
contain) abortErr.

 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.

 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.

 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.

 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.

 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.

 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.

 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.

 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.

use of register A0, which should contain a pointer to the driver when
called. Also added simple glue code for DrvrInstall and DrvrRemove since
none is available in the MPW interfaces.

 A5 in GrowZone Procs - If you have a grow zone function, it may get called
when a system routine is trying to allocate memory. 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.
