__getcwd(2) doesn't work like you think it works. It works by looking up things in the directory name cache. It's perfectly acceptable for it to fail. This is why you are supposed t use getcwd(3), instead, which can recover if the system call fails. Realize that directories do not have necessarily valid parent pointers hanging around. By overloading the lookup cache, I can cause your program to fail on NFS, as well, You just aren't waving the right dead chicken in your test case. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
