<<_fread_r>> is simply the reentrant version of <<fread>> that
takes an additional reentrant structure pointer argument: <[ptr]>.
<<fread_unlocked>> is a non-thread-safe version of <<fread>>.
<<fread_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
<<fread_unlocked>> is equivalent to <<fread>>.
