Rick,

You should try it. On many Unix systems it will work just fine. After the 
rmdir call, no call that uses a relative file name will work, however, 
since the directory must have been empty to be removed and in doing so the 
.. link would have been removed.

This applies to "classic" implementations on the Unix file system. Chris 
has pointed out that IRIX does not behave this way. Since those details are 
not part of the API specifications, the implementers get to do what they 
please. That's what it's all about when it comes to writing specifications 
(saying everything you mean and are willing to commit to and nothing you 
are not).
