The Comp.Sys.Mac.Programmer Digest is moderated by Mark Aiken
([e-mail]).

The digest is a collection of article threads from the internet
newsgroups comp.sys.mac.programmer.help, csmp.tools, csmp.misc and
csmp.games. It is designed for people who read news semi-regularly and
want an archive of the discussions.  If you don't know what a
newsgroup is, you probably don't have access to it. Ask your systems
administrator(s) for details. If you don't have access to news, you
may still be able to post messages to the group by using a mail server
like anon.penet.fi (mail [e-mail] for more information).

Each issue of the digest contains one or more sets of articles (called
threads), with each set corresponding to a 'discussion' of a particular
subject.  The articles are not edited; all articles included in this digest
are in their original posted form (as received by our news server at
ee.mcgill.ca).  Article threads are not added to the digest until the last
article added to the thread is at least two weeks old (this is to ensure that
the thread is dead before adding it to the digest).  Article threads that
consist of only one message are generally not included in the digest.

The digests can be obtained by email, ftp or through the World Wide Web.

If you want to receive the digest by mail, send email to

I was looking through Think Ref. and I stumbled across
SetDialogDefaultItem
and SetDialogCancelItem. It says that they aren't defined in the headers,
although CodeWarrior does have them. Is it safe to use them or should
they be avoided? Just curious.

I've used them with no problems in CW9 and CW10 with both 68k (native and
emulated) and PPC.

This is another example of a bug in Think Reference.  There's a technote
called Pending Update Perils where these routines were first introduced.
They have been in the headers for at least four years.  Unfortunately, the
Think Reference databases, while useful, haven't been updated in a long
long time.

Use SetDialogDefaultItem and SetDialogCancelItem freely in any modern
application.

There is a related bug in TR. The call SetDialogTracksCursor is named
SetDialogTrackCursor in TR (note the Track*s* in comparison to the Track).
Just to avoid confusion :)

Subject: Code snippet to find edge of main monitor?
Date: Fri, 27 Sep 1996 17:50:58 -0500
Organization: CampusMCI

Hi, I'm looking for a code snippet, either using PowerPlant or not, to find
the global coordinates for the upper-right corner of the main monitor. I
know how to get the desktop region using the qd global, but not to find
just the main monitor.

The reason for this is I want to be able to display a window in the
upper-right corner of the main screen by default.

Thanks in advance, and please feel free to email or post your reply.

here's the basic one-command approach to your problem.
(assumption here is that the main screen appears first in the device
list):

    theMainScreenRect = LMGetDeviceList()->gdRect

[this is code straight from my brain, you may need to add some type
casting]

btw, the official way of doing this is to crawl all the way through the
device list until you find the one with a specific flag set, but this is
around 20 lines of code and i can't make that without looking into a
book or two.

cheers!

GDHandle maindevice = GetMainDevice();
Rect bounds = (*maindevice)->gdRect;


The resulting "bounds" will be in global coordinates.
Note that GetMainDevice() may move or purge memory.

How about:
    theMainScreenRect = qd.screenBits.bounds;

I think the screenBits global variable is set to universally point to the
main screen's PixMap, and the looping is basically for finding the largest
screen, or performing operations which could affect multiple screens.

qd.screenBits.bounds is the virtual (!) rect that includes ALL screens
(useful for dragging windows and stuff). the tricky part here is that
parts of that rectangle may be simply unexistant, e.g. if you have a
832x624 (17") main screen and a secondary 640x480 (14") screen right to
it, qd.screenbits.bounds will be { 0, 0, 1472, 624 } - however the area
{ 832, 480, 1472, 624 } is offscreen.

>From the Macintosh Programming FAQ <http://www.best.com/~ckt/faq/>

5.13) Q: How do I get the rect of the screen?

A: Which screen? There can be many screens. The rectangle of the main screen
is qd.screenBits.bounds. The rectangle of all the screens is
(**GetGrayRgn()).rgnBBox. You should always post the rectangle covering
all
the screens to DragWindow(). This is well-documented in Inside Mac.


(and the "This is well documented" line is a hypertext link to this URL:

http://devworld.apple.com/dev/techsupport/insidemac/QuickDraw/QuickDraw-18.html

Inside Macintosh:Devices will also be a help here to deal with monitor
real estate (and just dealing with monitors).

Since you can get Inside Macintosh for free in electronic versions
(although the lack of a QuickView database for OpenTransport is
SORELY lacking...hint hint), little excuse not to have them and not to
read them :)  Enjoy!

Try:

Rect                        msRect;

mainScreen = GetMainDevice();
msRect = (*mainScreen)->gdRect;

How do you get a directory name from an Id?

This may seem like a stupid question, but I've been at it for over a day
now, and am getting a bit frustrated.  I have a dialog box, which allows
me to select a file I want to create (called from StandardPutFile() in
pascal).  It returns a file name, a parentId and vRefNum.  Now, I need
to get the FULL name of the file (including directory and volume name).
Does anyone know how to do this?

Could you please email any replies to
[e-mail], I don't check this newsgroup often.


Thanks,

I don't know if you are looking for the code in pascal but here is
something in C.

I'm still green so if this code is off the mark I'm prepared to hear
about it. :)

- -----------------------------
char *GetPathName( short vRefNum, long directoryID, char *pathName )
{
   OSErr          error;
   Str255         name;
   CInfoPBRec     pb;

   *pathName = 0;
   pb.dirInfo.ioNamePtr = name;
   pb.dirInfo.ioDrParID = directoryID;

   do

      pb.dirInfo.ioVRefNum = vRefNum;
      pb.dirInfo.ioFDirIndex = -1;
      pb.dirInfo.ioDrDirID = pb.dirInfo.ioDrParID;

      error = PBGetCatInfoSync( &pb );

Subject: Extension woes...
Date: 14 Oct 1996 18:41:18 -0400
Organization: America Online, Inc. (1-800-827-6364)

I'm finishing another extension/control panel, yet can't seem to get a
certain part of it to work.

I want to be able to open files and control panels, and the obvious
solution is Apple Events.  But, one mustn't send apple events from an
INIT, or...

This just hit me.  If the current application is Apple-Event aware, then I
should be able to send apple events from my INIT.  So, for example, if I
make the finder the front process, then attempt to send an 'odoc' (or
whatever) apple event, all should work.  Although, the finder is sending
and receiving...is this bad?

*OR*, I could write a little code segment, defined as such:
void    main(FSSpec mySpec);

I've seen some sample FKEY code that goes into its own WNE/GNE loop, so if
I already have that going, can't I send an Apple Event then?

This is a simple problem, but I want to do it the proper way (if there is
one?)

Thanks!

Alex Rampell

Not sure where you read this or what problems you're having, but an INIT
_can_ send AppleEvents, just not receive them because they don't have
event loop.

I have tried this from an INIT before with unfriendly results.  The way I
sent events from an INIT to an application is through the (obsolete?)
PostHighLevelEvent() call.  Otherwise I believe the apple events are
created in the application heap, which may or may not be valid from within
the context of the INIT.

If you need to send apple events, create a BOA that receives your custom
high level events and sends AppleEvents based on the data in the high level
events.  Effectively, instead of:

INIT --AppleEvent--> target Application

you will have:

INIT --HighLevelEvent--> Your BOA --AppleEvent--> target Application

You may be able to do some fancy SetZone() calls to get the apple events
into the system heap from the INIT, but I couldn't ever get it to work.

I hope this helps!

I think that should work.  However, it may depend on what your INIT does.
If you've patched jGNEFilter, say, it would probably be OK to send an
AppleEvent from the patch.  On the other hand, if you have patched a trap
that runs at interrupt time or is guaranteed not to move memory, you'd
better not try to send AppleEvents from the patch.

Having an event loop doesn't make it an application.  An FKEY still lives
as a "parasite" on some application's context.

Subject: Getting-Setting sound volume
Date: 15 Oct 1996 11:57:03 -0700
Organization: CRL Dialup Internet Access    [phone]  [Login: guest]

I'm trying to implement a menu for setting the sound volume in my
application. Sound Manager 3.0 introduces the SetDefaultOutputVolume and
GetDefaultOutputVolume calls. This seems like exactly what I want, but
I'm noticing two things that I need help with.

1)
Setting the volume to 0 does not turn the sound off. Inside Mac gave me
the impression that the sound would would be all the way off. The
constant for this value is called kNoVolume.

2)
The volume setting seems to be quantized to 7 steps, 8 including 0. No
volume is 0 and full volume is 256. If I set the volume to 32 and then
get the volume, it is set to 0. If I set it to 40 then it gets set to 37.
So, it seems there are 7 fixed possible values for the volume setting.

Some possibly relevant info, I'm using a IIcx with System 7.1 and Sound
Manager 3.0. I have not experimented with other systems yet. I'm using
the same value for both the left and right channels, which are in the hi
and lo words of the volume parameter.

BTW, I was attempting to provide command keys for 1-9 with 1 being
silence and then 8 levels of volume. Unless someone can tell me
differently, it looks like I'll have to settle for 1-8 without any silent
level.

I did this in SoundApp 2.1.1, however I've since dropped the idea.

On some Macs, e.g. my old Mac II, it does. On others, e.g. a Power Mac
8500, it doesn't. I think the kNoVolume was meant for the system alert
sound, which flashes the menu bar instead.

Indeed, this is quite annoying. Basically, it takes the "floor" of the
value on those systems which only support the old 0-7 sound volume. Thus,
you need to find out what the value of "1" would be, and use that instead,
and so on for the other values. Basically, use: n * 256 / 7 and round UP
always, (27, 74, etc.)

One Power Macs, you shouldn't do this as they support the fill 0-256. I set
the volume to 32 and then read it. If it came out zero, I did the 0-7 and
otherwise did 0-10.

However, this all fails on PPC Performas. Changing the volume this way
causes them to make clicking sounds continuously. I couldn't figure it out,
so I've since used the volumeCmd on my sound channel which always works.
This also allows you to over drive the volume. I support up to 150% for
those who like to live on the edge.

All (more or less) the PPC libraries, applications, and executable
binaries are in the same format, PEF.  (N.B. some older ones are in XCOFF,
an AIX format).  I believe that the CFM 68K libraries are in the same
format, but I don't know much about the 68K issues.

There is available via "downloadable license" (or whatever term these
lawyers have fabricated) the PEF specification from Apple.  This isn't
going to be very helpful unless you're trying to write a compiler or
similar (link editor, debugger, etc) utility.

I don't know about its legality for exportation.  Check :

Hello,
    I am looking for a library (PD or commercial) which will allow me to
extract the outlines of a TrueType font in a polygon vertex format.  I
need to create polygon text in a 3D application and need to be able to
use the fonts installed on the Mac.  Note: the application must be able
to run on a 68k Mac, so it will not use QuickDraw 3D.  I would prefer a
solution which did not use QuickDraw GX, but I will consider any such
libraries I can find.  If you know of anything which might fit the bill,
please let me know.

Thanks in advance.

On some of the developer cd's, there is a snippet called "QD Curves" (or
something like that) that contains C code that does what you request. It
will take a bit of effort to extract what you need, but most of the work
is done for you.

You can write C programs in UNIX too. You don't have to learn perl. I do

I think he means he wants a Mac C Compiler that produces a UNIX binary.
The problem with that is that there are SO many UNIX binary flavors. I
don't know of any Mac compilers that currently output UNIX binaries. It
shouldn't be too hard to move an ANSI project over to GCC on the actual
target machine though. That's how I usually do my UNIX projects. (Death to
vi).

There's a fundamental problem here.

"Unix" is usually used loosely[1] to refer to a broad class of OS's running
on dozens of different architectures. Which Unix do you mean? On what
processor? Using what executable format?

I believe that no matter the answers to those questions, the answer to your
question is simply: NO. The reason for this is that "Unix" is not a single
OS and does not run on a single type of processor. This is why much of the
common Unix software is chiefly distributed as source code, because the
variations between Unix machines are so great.

FWIW, it is perfectly possible to code CGI's in C on Unix. It is done all
the time. Unix has very good C tools.



[1] Technically, Unix is a trademark. It was owned by AT&T, sold to Novell,
and I believe Novell has since sold or sublicensed it to SCO or OSF or some
such bunch. There are somthing like 4 OS's that can legally be called Unix,
and even they run on a variety of platforms.

There isn't one to my knowledge.  One of the obvious reasons is that it
would need to generate binaries for different platforms.  If you have
shell access to the machine your CGIs would run on, check out the gcc or
cc man pages.  Gcc is an ansi compiler compiler so you could compose  with
BBEdit or CW and upload to compile.

Perl is a pretty simple scripting language.  If you know C you could pick
the Perl basics in less than an hour.

================

All examples available to me use some tools like
      "www.h",  "cgi.h",  "html.h", etc.
These are NOT available to me and I do not know where to find them. Can
somebody give me a pointer?

As an outsider and only an occasional user, I do not know how the server
passes the environment variables the cgi.c-script. All examples I have use
the function: something like
      getenv("content_length");

Is there any source code of PERL-interpreter written in C that is
available to the public? Be grateful if somebody can give me a pointer.

ResponderBuilder is supposed to serve the purpose but it relies on the
Coder-Warrior-plateform. Is there any one who successfully modified it to
Think-C-v5?

Occasionally, I downloaded some files with extention   .tar.z.   Stuffit
refused to un-compress them.  Mac-system recommended  ZipIt but my
Department does not have it. Is it a freeware? Where can I get a copy?

I wish to thank Nick.c who drew my attention to this newsgroup. Please

Hi all,

Quick question about THINK Pascal (v4)...

How do you Get/Set the menu bar height in THINK Pascal?
The function GetMenuBarHeight (or GetMBarHeight) is not
recognised, as well as the global variable MBarHeight.

Do I need to add some obscure library or interface file
into the project? I would have expected these to be part
of menu.p (which is, of course, supposed to be built in).

Thanks for any info!

This is taken from the header file Menus.h:

   TWOWORDINLINE( 0x3EB8, 0x0BAA ); /* MOVE.w $0BAA,(SP) */



Heres my code example of how to hide and show the menu bar, it may not be
the best example available, but it works for me.

short oldMBarHeight;
RgnHandle   mBarRgn,GrayRgn;
short MBarHeight;

   oldMBarHeight = GetMBarHeight();

   MBarHeight = 0;         /* make the Menu Bar's height zero */
   SetRect(&mBarRect,qd.screenBits.bounds.left, qd.screenBits.bounds.top,
         qd.screenBits.bounds.right, qd.screenBits.bounds.top + oldMBarHeight);

Which should be something like

function GetMBarHeight: Integer;
INLINE
    $3EB8,$0BAA;

in Pascal (which is what the original posted asked for). I havn't tested
this though.

You can also use straight Pascail code (from the SAT lib, hence the names):

 procedure SATSetMBarHeight (height: integer);
  type
   intPtr = ^integer;
  var
   ip: intPtr;
 begin
  ip := IntPtr(Pointer($0BAA));
             {the location of the 2-byte menubar height global var}
  ip^ := height;
 end; {SATSetMBarHeight}

 function SATGetMBarHeight: integer;
  type
   intPtr = ^integer;
  var
   ip: intPtr;
 begin
  ip := IntPtr(Pointer($0BAA));
             {the location of the 2-byte menubar height global var}
  SATGetMBarHeight := ip^;
 end; {SATGetMBarHeight}

Where do I find this utility (PICT Informer)?. I still am unable to find
documentation on how to find the number of colours in a PICT file. Where
can I get a description of all the fields/tags/format of a PICT file---is
there a web page for such graphics file formats?

Inside Mac 5 and 6 cover this.  Also Inside Mac:QuickDraw.

Check the Apple developer Web pages.
There's a couple of approaches to getting number of colors.
Use the PictInfo toolbox routines.  The main problem with these is
that if there isn't enough system memory they'll hang the machine.
The other is to set DrawProcs to record the colors.  There are
examples on Apple's develoepr CD's.  Check the web site.

I think that is fairly clear - I am just interested in a way

Reading the article on MacWorld's site on Apple possible auquistion of,
or partnership with Be, I had and idea.  Both companies have great
systems and both interfaces apeal to different people, after all we
don't all go around in the same car.  Now the PPCP platform is coming
out Be and Apple could do a first have two operating systems, that have
a unified set of calls.  What I mean is that a program writen for one
platform could work on the other.

I see the benefits as follows:

  - The user gets to choose the operating system of his or her choice
  - The user know that if they see a program for the Be it would
    available for the Mac and vice versa.  That way the user would
    not have to worry about the program not being available.
  - The programmer would only have to write and distribute one version
    of the program.
  - Apple and Be would compete between each other to provide a better
    system, while the user doesn't have to worry about buying a new
    version of the program every time they change their mind about their
    system choice.
  - A company deciding to allow the user to have the choice of system
    can by the same programs for both groups.


The only down sides are:

  - The programmer may have to do a bit more work
  - I might not have thought about the idea enough
  - I am probably being unrealistic.


That's, now for the views

I love the Be interface; anyone interested in having it now on their macs
should download BeView by Greg Landweber who wrote Aaron.

As for one programming working on both, it will be here sooner than you
think.  That is what all the hubub is over Java; it is a windows-oriented
(the concept, not the OS) programming language that can run an multiple
OSs.  Apple and Windows are both racing to support Java at the OS level,
freeing users from using Java viewers.  When that day comes, you should
see many, many programs coming out in Java that will run on both platforms
without modification.

There are still plenty of development work left for Java to supplant
C/Pascal as programming languages, but the groundwork has been done and
the OSs are moving in the right direction.  Be should support the Java
language as well.

One thing to keep in mind about Java apps is that there is great debate over whether
multi-platform GUIs will be supported with Java.  What I mean is many people believe
that Java apps should have identical GUIs across all platforms.  Which means no matter
what GUI you like to use on your platform, it won't be the same as the one in the Java
app.

This is just killing me. I can't seem to find anything on this...

If I grab a couple of strings from a STR# resource using
GetIndString(), how do I modify, then write back those strings to the
STR# resource?

None of my current Mac resources seem to deal with the topic of STR#
in any depth. Not even IM. Is this some sort of secret? Reading the
things is easy, creating them with ResEdit is a breeze... But writing
them to the Resource Fork must be magic.

Any help (or even better, pointers to references) would be
appreciated.

I suspect you have to use GetResource() and then modify the STR# Handle
directly, just like editing other resources.  You might find the Munger()
function useful for this case.

Yes, you could probably do something witih Munger(), but I shudder to
think what you would have to do :)

You can also try SetIndString() a little code snippet that I gleaned
from Apple DTS. (it follows):

The only change that I might make to this would be to change the
BlockMove() calls to BlockMoveData(), but that's just me (and shows
the age of this DTS snippet)

Someone wrote and posted a library of functions to work with STR#
resources a little while ago... have you tried searching InfoMac or
DejaNews?

If you don't use that code, you'll have to roll your own. It's pretty
easy. An STR# resource is simply a (short integer, 2-byte) count of the
number of strings, followed by that many Pascal-style strings with no
padding or anything. One way to do it: for each STR# resource create an
array of n StringPtrs, one for each string in the resource:

  Handle h = GetResource('STR#', id);
  if ( h ) {
      HLock(h);
      short count = *((short *)*h);  // get the count
      StringPtr *strings = new StringPtr[count];

      // loop through strings setting up pointers

      StringPtr p = StringPtr(*h + sizeof(short));

      for ( short i = 0; i < count; ++i ) {
          strings[i] = p;
          p += *p + 1;  // point to next string
      }
  }

Whenever you change a string, replace the pointer with your string:

      strings[k] = mynewstring;  // a Str255, StringPtr, whatever

Then to create a new resource, add up the sizes and copy the strings to a
new handle. You could be keeping track of the total length as you change
the strings, too.

      Size maxsize = (count * 256) + sizeof(short);  // max rsrc size
      Handle new_h = NewHandle( maxsize );
      if ( new_h ) {
          *((short *)*new_h) = count;
          StringPtr p = StringPtr(*new_h + sizeof(short));

          for ( short i = 0; i < count; ++i ) {
              if ( strings[i] ) {
                  memcpy(p, strings[i], strings[i][0]);
                  p += strings[i][0] + 1;
              }
              else
                  *p++ = 0;  // empty string
          }

          // replace the old resource data with the new

          Size thesize = Ptr(p) - *new_h;
          HUnlock(h);
          SetHandleSize(h, thesize);  // should check result
          memcpy(*h, *new_h, thesize);

          WriteResource(h);

          DisposeHandle(new_h);
      }

That's a sloppy online version, but you get the idea. I'd look at that
STR# library first.

Hello:

In my application, I'm trying to set the device-- the microphone-- to
11KHZ before recording.  I'm using the SPBSetDeviceInfo call but am
getting a -225 error each time.

I've put many different variations of the desired sample rate in the
third variable of the function.  I've tried typecasting, pointers,
addresses, and countless parenthesis.

Has anyone successfully used this function?  Can anyone help me?

A quick look at Errors.h tells us you're getting "siInvalidSampleRate"
which seems logical. So you must be attempting to set the hardware to a
rate that it cannot support.

Have you tried to use the siSampleRateAvailable selector to find out which
rates are actually supported by the device your using?

> Has anyone successfully used this function?

Of course.

I ran into this very problem, and my solution was to query the device on
what sample rates are supported, and then either a) insure my rate is
between the supported rates, or b) choose the closest rate available. It's
a lot of code, but you can do it once at the beginning of the program if
you use a single rate.
(I don't. Sure would be nice if we could have a "closest match" rate...)

You must pass a Fixed value! (which is not the same as a long, which is
why the numbers make no sense when viewed.) This works:

Fixed rate;

rate = Long2Fix( 11000 );
err = SPBSetDeviceInfo( soundRefNum, siSampleRate, &rate );

Hope this helps!

Actually it's not quite a Fixed number. The high bit = 32767 (I think).
It's sort of an unsigned fixed. This is important for values greater than
32Khz (like the ever important 44.1kHz and 48kHz).

(I posted the text below to Symantec tech support this morning, but it
occured to me that I can probably get a much quicker responce here.)

I just replaced my old Project manager with the new one on the "Symantec
Cafe DR1" CD-ROM. Now it refused to compile C++ source code.

I assumed that it was a superset of the old project manager. Was I
wrong?

If so, how can I manage both C++ and Java projects on the same disk,
when the Mac automatically chooses the application when I double click
on a project file? If one is not a subset of the other shouldn't the
Java project manager have a different Creator code than "SPM"?

D'oh.

Yup. I think the fact that the DR1 SPM is Java-centric is documented in the
release notes. The DR2 SPM works for both.

The original intent was to have a single SPM that would work for both,
though due to pressures from upper management to get something to market we
had to cut corners.

You can't. Make alii on your desktop or use a launcher.

This was debated hotly, and it was decided not to do this for a number of
reasons, one of the most compelling being that changing the creator would
have detrimentaly effects on existing scripts and external tool support.

Hmmm, I think a charge of pedantry could be levelled against Mr Emerson.
Fowler* says that while there is no hard and fast rule, "... there is a
tendency to abandon the Latin plurals, and that, when one is really in
doubt which to use, the English form should be given preference." The OED
gives "aliases" as the plural and doesn't have "alii" as an alternative. Is
there a dictionary that prefers the latter form?

* In "Modern English Usage" under "Latin plurals".

Much ado about nothing. The plural of alias is aliaii. Monsieur Emerson
was then extrapolating to somewhere around the year 2019 where the middle
syllable is dropped (common words are compressed to as few syllables as
are intelligble).

Hi all,

I can't find where the function HasDepth is declared.
It belongs to QuickDraw/Graphics Devices, but I cannot find it in all
the interface files, neither the old ones (preferred!) nor in the
Universal Headers.
Unfortunately, the trap number isn't given in Inside Mac either.

Who can help?

It is in Palettes.p (at least in the old interfaces).

Use BBedit to search through the interfaces. It will find the right
interface file in seconds.

The subject says "Think Pascal", where we rather say:

Palettes.p happens to be the right interface, but the C and Pascal interfaces
sometimes differ.

Hopefully this should be fairly self explanitory.  They seem pretty
quick in my tests on a 7200/90 with CW10.

Transparant_Cheap16bit_Blit() produces slightly darker results than the
more expensive Transparant_16bit_Blit(), which takes account of the
least significant bits.  They work on two pixels at a time, and no
attempt has been made to get these to work with odd x paramaters.  It
would be trivial to get this to work with 32bit colour.

If you want a real challenge, try writing a fast routine to _add_ two
24-bit pixel values with saturation (32-bit ARGB format, alpha ignored).
e.g.

pixel 1: A = ??   R = 22  G = 201  B = 88
pixel 2: A = ??   R = 66  G = 179  B = 11  +
___________________________________________
result:  A = ??   R = 88  G = 255  B = 99     (G saturates to 255)


Note that the carry bit from G is not allowed to overflow into R. I found
a way to do this in the general case with just 8 arithmetic/logical
instructions, no branches, 6 cycles on a 604. A related technique gives
bytewise min/max algorithms with similar efficiency. See if you can find
the algorithm I used!

Indeed it does :)  The channels do not interfere with each other in any
way.

If you don't care if an overflow causes the channel to the left to
increase by 1 (still pinned to 0xFF), e.g.

11 33 BB +
AA 44 AA =
________
BB 78 FF  (green channel one shade lighter due to red overflow)


then you can do it in 7 instructions. If the red overflow causes green to
overflow as well, then blue will increment by one, e.g:

11 FF FF +
AA 00 01 =
________
BC FF FF (red overflow winds up incrementing blue by one)

An eighth instruction is required to avoid this channel interference in
all cases.

Does it handle correctly the case where the low byte overflows and the
middle byte adds up to FF?  Example: 123456+AACBAA should make BCFFFF.

You can patch a trap to do many different things.
A typical example is to fix a bug, ie a trap doesnt preserve registers
correctly after completion, So you could patch the trap to save registers
and restore them after the call.

You could patch the shutdown trap and add a routine to back-up some data.

You could patch the SysBeep trap to disable sounds during certain times of day

You could patch the disk insert trap to eject the floppy disk, thus
rendering the A. driver uselss - Sys Admin's may not want anyone to insert
floppies onto Networked machines.


..... etc....etc....etc....

The address isn't fixed. Develop had an article on writing directly to the

    That being said the simplest method is to create a window on the

Where can i find this article please, because i live in France.

because i can get the base addresse with the function

I suggest that you:

1) Make a window (easy peasy, GetNewCWindow)
2) Allocate a GWorld (Apple has lots of nice sample code for this)
3) Render your graphics in the GWorld; you can access it completely
without violating any Apple guidelines
4) Use CopyBits to blast your GWorld onscreen every frame

This method is Apple-sanctioned yet still quite fast.
Have fun!

yes, but we can get this address with the function GetLMScrnBase() with
codeWarrior.

but it's too slow for a fast animation.

with a Mac IIci it take 1.2 sec for draw a large Rect on the screen with
a pointer.

can't we draw offscreen and then change the ScrnBase, or directly draw
into the VRam.

thank you for this answers.

QuickDraw doesn't use any special technique that you can't use!
It just writes to screen as well.

What kind of pointer did you use? (byte *)? This will be slow.
Byte-for-byte copies are not very optimized.
Try (long *). Also, try unrolling loops.

Drawing to ScrnBase is writing directly to VRAM!

Repeat 100 times:

    The Macintosh is not an Amiga

(This request is because I think the Amiga is one of the few "modern" machines
where video can be placed just about anywhere in RAM.)

Then read the Inside Mac material on QuickDraw and Graphics Devices
until you fully understand the issues involved. The low memory variable
that you mentioned is only the tip of the iceberg and once you know
how to program Mac video directly, you will never even think of using
it for anything.

Also, if drawing something on screen takes your code 1.2 seconds on a IIci,
then there's a serious problem with your code and how it is organized.

     Actually many "home systems" did allow this, the 8-bit Atari's alowed
many of flipping techniques. One of my complains of new systems( both Mac
and Intel), is the waste speed. In an old 8-bit I could page flip three
images for animation, with some tricks I could get all 256 colors on
screen, and even more get to draw offscreen while moving current view(
this was helpfull for scrolling). I know it could all be "simulated" on my
Mac, but three lines of code was all I needed back then.

Why not just write your app as an OpenDoc container and allow the user to
use whatever word processor they want? Then they can plug in WAV or
Apple's text editor, or the Cyberdog text editor, and you don't have to
worry about writing one yourself!

Subject: [BETA] fast memory allocator and debugging tool
Date: Sat, 12 Oct 1996 15:19:23 -0500
Organization: Biit, Inc.

Biit, Inc is looking for a few beta testers to help test HeapManager. See
description below.

To be put on the beta list, please send your contact information, and a
brief description of the application(s) you would be testing HeapManager
with, to [e-mail]. Complex applications that create/delete large
number of objects are particularly useful. The debugging features of
HeapManager need the most exercise.

General information is available at our website <http://www.biit.com>.

HeapManager is a fast memory allocator library and heap debugging tool for
Macintosh C and C++ applications (68K/PPC) developed with Metrowerks
Codewarrior. Applications written in C++ that call operator new, and those
C applications using malloc() to allocate memory, will see performance
gains ranging from modest to dramatic (depending on how often the
application allocates/frees memory). See the website at
<http://www.biit.com> for benchmark results of testing most of the
commercially available allocators (Metrowerks, Microquill & Biit).

HeapManager also supplies a comprehensive heap checking and debugging API
to help detect memory leakage, over- and under-writes, writes to
previously freed memory, double-frees and uninitialized memory. Additional
routines collect runtime memory usage statistics such as total allocated
memory, popular allocation sizes, and others.

Use of the debugging features is made easier by the presence of HeapBoss,
an external application that can control the debugging library remotely,
display heap settings and statistics, automatically check the heap, and
record memory allocations to assist in leak detection and help track
memory usage. HeapBoss is designed to work in conjunction with the
Metrowerks Source Debugger, but can also work standalone.

To those who are familiar with Microquill's SmartHeap, HeapManager
provides similar performance, a somewhat different feature set, and also
includes an external debugging application (Microquill only ships their
HeapAgent on Windows.X platforms, and for an additional charge).

Note that HeapManager does not replace or debug the MacOS memory manager,
nor does it assist applications that only call NewPtr() or NewHandle().

HeapManager will be priced at $99 when it ships.

Hi,

are there any plans to develop versions of HeapManager for other platforms
like Win32, Solaris..., similar to Microquill's SmartHeap ?

Just curious,

Internally it is written to be platform-neutral. However I don't expect it
will be ported in the near future; the other platforms are *much* harder
to develop this kind of product for, and the competition is very well
entrenched. It would really depend on how much demand there will be once
HeapManager is shipping.

Focusing on making Macintosh applications faster & cleaner makes the most
sense right now.

You can call the (apparently undocumented) function __InitCode__. You'll
need this in your code:


extern "C" {
   extern void __InitCode__(void);
   extern void __destroy_global_chain(void);
}

...

EnterCodeResource();
...
__InitCode__();  // call one time only

...

__destroy_global_chain();  // call when your code resource is disposed


I can't find any reference to this in the CW docs, but it certainly should
be somewhere. You can find the source among the various startup code
sources buried in the Mac OS Support folder.

The answer depends on your development environment.

I use CodeWarrior. The documentation is reasonably complete, though it's
mostly in the sample code :-)

My experience is that (once things are set up correctly) static
initialization happens automatically. Setting things up correctly mostly
involves making the correct settings in the preferences dialog.
[Unfortunately, I'm not at my development system now, so I can't specify
the details.] One of the useful options is to request the "extended" code
resource format, and there are some useful macros in SetupA4.h that you
need to use.

I hope this is enough to get you started.

Alain, I believe this is the primary reason it's called PhoneNet.  Typical
telephone wiring in homes (modern wiring, that is) has 4 wires, but your
phone only uses two.  So the other two can be used for a second line or
another special purpose.  Your PhoneNet connectors, if connected to the
opposite pair, should let you do what you're attempting -- with a little
tinkering and wire-studying.  The wires are red, green, yellow, and
black.  I'm not sure (it's been a while), but I believe that the
yellow/black pair is the first one used, and if you're in a single-line
home the red/green pair is available.

Hope this helps.

PhoneNet uses the outer two wires (normally yellow/black) in a standard 4
conductor phone extension.  You can use the inner pair (normally
red/green) for a telephone connection.  I "inject" the phone by plugging
the telephone line into the unused side of the PhoneNet connector and take
it out the same way at the other end of the link.  A "proper" installation
would connect a 72 ohm resistor acrouss the outer pair on the phone line
connectors, but you may be able to get away without it; I do.

I wouldn't be so quick to abandon Hypercard. I would suggest possibly
investing in CompileIt!. It's a Hypercard based compiler that you can use
to write XCMDs and XFCNs (and actually just about any Macintosh code).
This way you can write actual Macintosh code, just as you would with C or
pascal, but it's a much easier language to learn. And you would have the
benefit of using that code in a Hypercard stack instead of trying to write
your own applications which could be a huge project. Animation is more
than a little tricky. I would suggest trying it with Hypercard alone
first. Try scripting buttons to move about the screen, etc... There are
countless Hypercard game stacks out there- search the web and dowload
some. You'll find they range from very basic to very refined.

Latest CodeWarrior has an in progress Game frame work called
GameWerks.  He can get the student discount.

There are a few Mac Game programming books.  Tricks of the Mac Gamming
Programming Gurus by McCornack, Ragnelmalm, Celestin, etc from Hayden
Books is probably the best all around one.

There are some demo games on there.  Also do a check in the info-mac
and alt.sources archives.  Best thing might be to get a handle on the
C language and get some example code to modify.

Fellow Dave, you can find MacsBug on apple's web page system.  Go to
http://www.devworld.apple.com/
And click on the "FTP" link.  You'll be then taken to a page which has
a bunch of links for each letter in the alphabet (give or take).  Click
on the one which contains "Macsbug", and it'll take you to a page which has
a URL for Macsbug.  It sounds complicated, but it's not.  The version there
is 6.5.3.  I don't know if it's the newest one or not, but I've had difficulty
getting it to work on my PPC....
