Re: My private problems

[Jens Alfke]

To resolve symlinks in paths, call
-[NSString stringByResolvingSymlinksInPath:]

This is declared in NSPathUtilities.h, which makes it easy to  
overlook...

That the /private prefix is removed is documented behavior.

I think that will work.

Actually, that won't. You have to write a special case still to  
handle if

the symbolic link is absolute.

What are you trying to accomplish, exactly?


I want to call statfs(), and had previously concluded that it does  
not follow symbolic links. It seems that on 10.4.11 this is no longer  
true.


So - just for fun - how can I convert the symbolic link "/tmp" into  
an absolute pathname?

stringByResolvingSymlinksInPath leaves it unchanged.
pathContentOfSymbolicLinkAtPath returns a relative path.
What to do?


Kind regards,

Gerriet.

I need an absolute path.

So I do:

NSFileManager *fima = [ NSFileManager defaultManager ];
NSString *fileType = [ [ fima fileAttributesAtPath: path   
traverseLink: NO

]; fileType ];
if ( [ fileType isEqualToString: NSFileTypeSymbolicLink ] )
  path = [ fima pathContentOfSymbolicLinkAtPath: path ];

The problem is: "/tmp" is converted to  "private/tmp" (Note the  
missing

slash at the start).



Well, it's not "converted". In OS X, "/tmp" is a relative symbolic  
link.

-[NSFileManager pathContentOfSymbolicLinkAtPath:] calls something like
readlink(2) behind the scenes. So what you get back is the content  
of the

link... which is a relative directory name.



Short of hardcoding a change from "private" to "/private" -
is there some Cocoa (or Carbon or bsd or whatever) way to get "/tmp"
converted to  "/private/tmp" (with the leading slash) ?
(Same problem exists for /etc and /var).



You can do this:

[[path stringByDeletingLastPathComponent]
stringByAppendingPathComponent:[fima pathContentOfSymbolicLinkAtPath


:path]];



I think that will work.


Not if the link point to an absolute path.

NSString *absolute = [fima pathContentOfSymbolicLinkAtPath:path];
if (![absolute isAbsolutePath])
absolute = [absolute stringByAppendingPathComponent:absolute];
