Re: getwd not available

[Scott Klement <c400-l@xxxxxxxxxxxxxxxx>]

Whether or not it's safe depends on the assumptions made when calling 
the function.  If all callers ensure that 'buffer' has at least 1024 
bytes available, then your macro should work.  If they make different 
assumptions, there's a chance of overrunning memory.

Assuming that you're doing this to port existing software, I'd grep (or 
FNDSTRPDM) the software for everywhere it calls getwd, and see how those 
vars are defined.

If you're doing this for new software, please just use getcwd in the 
first place.  Don't use getwd.
