You would probably use the functions outlined here:

CoreEndianReference/index.html#//apple_ref/doc/uid/TP40002223
Most notably the LtoN (little endian to native) functions.

Hi,
I have just ported my app to Mac-Intel. It works pretty well
excepted for
some part. For example, when I earlier compiled for the Mac
platform only, I
had to convert some float, read from a win file, to the big
endians for Mac.
Now, for the Mac-Intel version I check #ifdef __LITTLE_ENDIAN__
then I don't convert the float to big endians, and this works well.
That was easy because I know that the data come from a win file.
But as I have seen, now I have to convert some other variables to
the little
endians when #ifdef __LITTLE_ENDIAN__
So I ask to myself, what should I convert?
How to determine the variables I have to convert to little endians
and the
variables I can quite leave as they are?
In my code I use QuickTime, OpenGL, Cocoa, C, ObjectiveC.
Thank for any suggestion.
