The functions you're looking for are in unix-bytestring[1]. They also 
have precedent on the System.Posix.IO.ByteString module name, but there 
was a bit of a mixup back when the ByteString-based filename stuff was 
introduced in unix.

The unix-bytestring package was always intended to be rolled into unix. 
When I proposed incorporating it back in the day, the original version 
mirrored the System.Posix.IO API and the proposal was voted down because 
noone liked the System.Posix.IO API! I've since redone the API to better 
match the POSIX standards, and have gotten positive feedback on it. So 
perhaps it's time to revive the proposal for inclusion.
