Paulex, I don't thin it's necessary. Even if stdout/stderr are not
redirected,
RI still returns inherited channel as long as stdin is redirected on
Linux.
OK, thank you. Another question(please forgive me, just for curious),
how about only stdout is redirected?

Any chance to get non-null value if inetd is dummied on Windows? Seems
some Services for UNIX(SFU) is provided by MS with Windows server 2003,
which can mimic the inetd behavior[1]. I'm not sure if it applies to
WinXP, too.
