I did realize that it might be returning 0 and modified my code to check for defined values but that didn't make any difference... plus it's really not possible for a pipe to have a buffer size of 0 so that's just not a valid result.

As stated, I need to use fileno(). So simple... in hindsight

Thanks all!
