volume of POSIX.1‐2017 defers to the ISO C standard.
The getwchar() function shall be equivalent to getwc(stdin).

Использование в приложениях (Application usage)
If the wint_t value returned by getwchar() is stored into a
variable of type wchar_t and then compared against the wint_t
macro WEOF, the result may be incorrect. Only the wint_t type is
guaranteed to be able to represent any wide character and WEOF.
Обоснование (Rationale)
