The <<stdio>> functions maintain an error indicator with each file

<<ferror_unlocked>> is a non-thread-safe version of <<ferror>>.
<<ferror_unlocked>> may only safely be used within a scope
protected by flockfile() (or ftrylockfile()) and funlockfile(). This
function may safely be used in a multi-threaded program if and only
if they are called while the invoking thread owns the (FILE *)
object, as is the case after a successful call to the flockfile() or
ftrylockfile() functions. If threads are disabled, then
<<ferror_unlocked>> is equivalent to <<ferror>>.
RETURNS
<<ferror>> returns <<0>> if no errors have occurred; it returns a
nonzero value otherwise.

PORTABILITY
ANSI C requires <<ferror>>.
<<ferror_unlocked>> is a BSD extension also provided by GNU libc.
No supporting OS subroutines are required.
