Re: Finding hardlinks

2006-12-23 Thread Mikulas Patocka

If user (or script) doesn't specify that flag, it doesn't help. I think
the best solution for these filesystems would be either to add new syscall
int is_hardlink(char *filename1, char *filename2)
(but I know adding syscall bloat may be objectionable)


it's also the wrong api; the filenames may have been changed under you
just as you return from this call, so it really is a
"was_hardlink_at_some_point()" as you specify it.
If you make it work on fd's.. it has a chance at least.


Yes, but it doesn't matter --- if the tree changes under "cp -a" command, 
no one guarantees you what you get.

int fis_hardlink(int handle1, int handle 2);
Is another possibility but it can't detect hardlinked symlinks.
