Is it possible to do the inverse of mmap?
That is, suppose you have some data, like
  void* data
with a length

              Does anyone know how to add and remove tabs using
LTabControl on the fly...
Or have some snippets of code for the same ? If you have please post on
the group.

I'm just getting started programming on the Mac OS X platform, and to
be honest, I haven't had time to _really_ dig into apple's developer
site. I did do some surface skimming and reading of some newsgroup
posts, and one thing isn't clear to me at all: (if this is an FAQ, just

I have one window in resource file and I want to use it as modal or
non-modal according to situation, I don't want to create two similar
windows with one difference one Regular and one modal. So I need to
change Layer parameter from modal to Regular or from Regular to modal

Just upgraded from Panther to Tiger. I'm running into the following problem:
when installing the BSD SDK package, I get an error message saying the
installation failed, please try again.
Anyone knows what could cause this problem or where to look at ?

I've been programming for many years on PC, the last 8 of which have
been spent in commercial Java development.
I've just bought a Mac mini at home, to complete the 'switch', and would
like to start development on some personal projects to start with.

it seems that the update to OS X 10.3.9 made my built broken.
I have still XCode 1.5.
I get the following error:
Syserror 2 at CarbonSound/CarbonSound.r

In Windows land, there's a standard save/load dialog that's available to
 programming. Under Carbon, is there something similar? I would assume
there would be. If someone has examples that utilize this, that'd be
great. Thanks in advance! It's actually good to be making progres. ...

If I already have a .nib file and I want to add a new window to that
NIB, how do I do it? If I do file/new, it just creates a new .nib file,
and any attempted reference to the resource doesn't resolve (it can't
find the name of the new window I've created).  I accidentally did it ...

I'm currently trying to port a small dialog based application from
Windows over to OSX. ACcording to all of the documentation I've read, a
Carbon app is the correct thing to use, so that's what I've started with.
I've managed to create a nice window in Interface Builder that is

How do I get an NSStepper to send its action?  Since it's made up of
two buttons, do each of the buttons have a separate target?  Or does it
inform its target that one of its buttons has been pushed, and you get
the value from it?

I installed Tiger yesterday and the disk says "Includes XCode 2".
However, the default installation doesn't put it on the hard disk.
How do I install it?
Cheers

I'm making a 'Read Me' for my app, and of course include a link to my
web site and email, but how can I make said link clickable?  I have seen
other read mes that do this in RTF files, but don't know how...
Thanks!

I had a look at the generated code from a small program that I wrote
that just added two vectors and printed the results and noticed an
extra four to six instructions around the load and the store and was
wondering what these are for.

    I just try to compile the code from:
http://developer.apple.com/samplecode/GetPrimaryMACAddress/GetPrimaryMACAddress.html
    There is a c file in the archive which I compiled with:
gcc GetPrimaryMACAddress.c -framework IOKit -framework CoreFoundation
