Hoogle does not search the Posix library, because in general people
should steer clear of it - otherwise I won't be able to run your
programs :-) - The next version of Hoogle will permit selecting to
search the Posix library, if you so choose.

Clearly, the documentation is rather weak. It comes from the Posix
"open" function, which is document all over the place, and you can see
the code here: http://darcs.haskell.org/ghc-6.6/packages/unix/System/Posix/IO.hsc
After figuring out what you want, I recommend submitting a patch for
documentation. Additionally, if what you want can be done in a cross
platform way, but lacks the appropriate abstraction layer, I would add
a request for this to be fixed.
