I have printed the values LDBL_MAX_10_EXP LDBL_MIN_10_EXP and i have
obtained 308 and -291 while DBL_MAX_10_EXP DBL_MIN_10_EXP are 308 and
-307. Shouldn't the values for long double be much bigger or at least
equal to those of double? Furthermore how is it possible that

I am having trouble with manually decoding a quicktime file.  An
application I have outputs sound files in quicktime format.  The data
stored in them is 44.1 kHz 2-channel 16-bit audio, and I need to convert
the file format to WAV for further processing.  This should be fairly

I'm helping (!?) my wife learn C, and she's stumbled over a missing
include file, #include <iostream>.
She's working from the terminal, and has Xcode 2 installed. It's gcc
4.0, and the include file is there:

I'm very new to Cocoa and Xcode, so this is a pretty basic question,
but I've searched the web and Apple's built-in documentation for
several hours now with no luck.
When a window redraws, I want to execute the following code to draw its

This is going to sound silly, but well, I've reached the end of my
patience hunting for the answer. Here goes:
I'm trying to learn C++. I'm running OS X. Can someone point me toward
a resource (or just tell me -- I'm quite willing to have the answer

I'm linking a static library (freeimage.a) against my OS X application
(Xcode). The static library throws an exception (throw [number]) I want
to catch in my application. How can I propagate this C++ Exception into
my program? Is there any compiler switch?

(appologies if this posts twice, I don't normally use OE)
I have a NSImageView in a window. In the class, I want to find out the size
of the NSImageView so that I can allocate a NSImage of the correct size.
I've tried code like this, the NSImageView is myView:

How can I inspect an objective c object in GDB if the code I'm tracing
doesn't have debugger symbols?
For instance, I've got QuickTime Player loaded in GDB, and at one point
I stop just before a call that passes an NSDictionary to another

I think iTunes' movie player really stinks, so I'm trying to write a
replacement player that plays files from the itunes library. (That way,
I don't have to worry about managing ipod syncing.)
Is there an approved way to play a Fairplay mp4 file? I'm talking about

I have an uncompressed MONO stream of 16 bit samples in this Windows app
I am writing, and I am trying to write it to a QuickTime movie using the
Windows QT SDK.

Hi there :-)
I am looking for GNAT or other ADA-95 compiler for my old 68k Macintosh.
As I have found out, the version of GNAT working on mac-68k should be 3.04
and  possible name of the file could be one of those:

I am trying to make a customized open file dialog that allows the
opening of files that need root permissions, eg a file like
/etc/httpd.conf.  I can use the Authorization API to prompt a user when
saving the file. But if I use a regular open dialog, all those files are

I have several problems writing my own little screen saver.
I'm going to start with the first one for the moment ;-)
It seems to me that plists are very limited in size -- could that be?
I've got a plist (happens to be from my screen saver).

I'm trying to link a very simple code interface node for LabVIEW 7.1,
and Xcode 2.2 generates a rather cryptic error that I have no clue
about sometime during the final link steps:
   Command /Developer/Private/jam failed with exit code 1

The default directory of a Carbon OS X application as used by stdio
seems to be at the level above that of the named app directory.
But MakeFSSpec() seems to assume that the default directory is
down in the ./appname/Contents/MacOS/ subdirectory, so can't
