<<_fwrite_r>> is simply the reentrant version of <<fwrite>> that

<<fwrite_unlocked>> is a non-thread-safe version of <<fwrite>>.
<<fwrite_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
