-- | Access to the BSD sysctl(3) interface
--   
--   This module provides efficient access to the BSD sysctl(3) interface
--   via the Haskell FFI. It allows to read and write both basic sysctl
--   types, as well as complex opaque types described via Storable
--   instances.
@package bsd-sysctl
@version 1.0.0


-- | This module allows access to the BSD sysctl(3) interface via the
--   Haskell FFI.
--   
--   Convenience functions to read and write the usual sysctl types are
--   provided, as well as more advanced functions to handle binary values
--   given a suitable Storable instance. It is also possible to retrieve
--   data whose size changes at runtime with the <a>sysctlPeekArray</a>
--   function.
--   
--   Nodes may be queried either by their name, their OID as a list of
--   <a>Int</a>s, or by an OID returned by <a>sysctlNameToOid</a> if speed
--   is a concern.
