No, certainly not. Are you famaliar with C? A fd is something you get back when you use the system call open() on a file. It is even more low-level than the usual C FILE*. A description can be found in K&R2 chapter 8. If you don't have it or something similar, I have K&R2 as html and pdf file available, mail me when you want a copy. -- ir. J.C.A.
