Redirection of STDOUT/STDERR/STDIN is handled by command shells, and outside the scope of the process being exec uted. In general, I don't think that it is possible for a process to know where its STDOUT is directed. It is sometimes possible to determine whether STDOUT is a terminal device, but that tends to be system dependent. > > *any* clues would be most appreciated.
