yes, I have done checking both of the leopard and tiger's darwin
sources, before I ask to the mailinglists.
You are asking to the *wrong* mailinglist. This one is for Cocoa
(Foundation/AppKit/etc.) programming. Your question is about lower-
level POSIX/BSD APIs. Check lists.apple.com and look for a more
appropriate list, please. That way you're more likely to find someone
who knows the answer to your question.
