DESCRIPTION
<<getwchar>> function or macro is the wide character equivalent of
the <<getchar>> function. You can use <<getwchar>> to get the next
wide character from the standard input stream. As a side effect,
<<getwchar>> advances the standard input's current position indicator.

<<getwchar_unlocked>> is a non-thread-safe version of <<getwchar>>.
<<getwchar_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
<<getwchar_unlocked>> is equivalent to <<getwchar>>.
The alternate functions <<_getwchar_r>> and <<_getwchar_unlocked_r>> are
reentrant versions of the above. The extra argument <[reent]> is a pointer to
a reentrancy structure.
