porting UNIX file utilities to OS X? (HFS+ questions)

[Will Benton]

Hi all,

I'm interested in porting some file synchronization code from Linux
(basically, entirely ANSI C/POSIX) to OS X. However, I want to enable
my code to deal gracefully with multiple forks and any other
idiosyncracies of HFS+. (That is, if I copy a file with resource
forks to a Linux machine using my tools and then copy it back to OS X,
I want the forks to be preserved by my tools.) Therefore, I have
three questions: where's the best place to start looking for
documentation to get up to speed on these issues and the relevant
parts, I assume, of the Carbon API? Is there any good example code?
What else do I need to know about HFS+?




thanks,
wb

Aren't there PD utilities to deal with Mac files already?
Maybe look at the implementation of Rez / DeRez and CpMac / MvMac
(if they're available... darwin vs. os x, I guess, sorry)
