I don't believe that POSIX compliance is a sufficient argument to ask 
someone to shut up in the discussion of a cross-platform API. Which is 
more or less what James' answer was trying to do. So, no, not exactly the 
same thing that I said.

I'm not sure that's true. Various Unix/Linux man pages are readily 
available on the Internet, but they regard specific implementations, 
which often depart from the spec in one way or another. POSIX specs 
themselves don't seem to be easily reachable; you might even have to pay 
for them.

cheers
