System.Posix.IO.ByteString.fdRead :: Fd -> ByteCount -> IO (String, ByteCount)
which is identical to the one above. The ByteString in the module name suggests it would be using ByteString instead of String?
Can anyone explain this for me?
The "ByteString" in the SYstem.Posix.*.ByteString modules applies to the pathnames (POSIX pathnames are byte strings, and there's lots of ways to cause problems if you insist on pretending that they are in any particular encoding), not the values being read/written, so functions like that are basically carried along just to provide a mostly compatible API. I would expect to find functions working with ByteString values under Data.ByteString. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
