Hi , I was working on Mac symlinks(unix style) and encountered things I couldn't find information on through web searches. I was thinking these are Mac specific flags and meanings, so with that intro: when you lstat() a symlink, lstat states that st_size will be the size of the pathname for the link, what does it mean when it is a link with st_size = 0, yet it does have a link?
I believe that the st_size of a symlink is a filesystem implementation detail. You should not rely on it for anything serious.
That may be, but it's still in POSIX: http://pubs.opengroup.org/onlinepubs/009695399/functions/lstat.html
I just verified on my own system that it is working correctly for an HFS+ filesystem. The OP may wish to verify his own code is working correctly by comparing his output to that of 'stat -x {file}'
I had only found one instance so far where the Mac returned st_size = 0. I didn't wish to assume anything! The case was in testing "/dev/stdin" which has relative link to "fd/0". _______________________________________________ Do not post admin requests to the list. They will be ignored.
