-- | The 'catchIOError' function establishes a handler that receives any
-- 'IOError' raised in the action protected by 'catchIOError'.
-- An 'IOError' is caught by
-- the most recent handler established by one of the exception handling
-- functions.  These handlers are
-- not selective: all 'IOError's are caught.  Exception propagation
-- must be explicitly provided in a handler by re-raising any unwanted
-- exceptions.  For example, in
--
-- > f = catchIOError g (\e -> if IO.isEOFError e then return [] else ioError e)
--
-- the function @f@ returns @[]@ when an end-of-file exception
-- (cf. 'System.IO.Error.isEOFError') occurs in @g@; otherwise, the
-- exception is propagated to the next outer handler.
--
-- When an exception propagates outside the main program, the Haskell
-- system prints the associated 'IOError' value and exits the program.
--
-- Non-I\/O exceptions are not caught by this variant; to catch all
-- exceptions, use 'Control.Exception.catch' from "Control.Exception".
