20 The functionality described on this reference page is aligned with the
21 ISO C standard. Any conflict between the requirements described here
22 and the ISO C standard is unintentional. This volume of POSIX.1‐2017
23 defers to the ISO C standard.

25 The getwchar() function shall be equivalent to getwc(stdin).

39 If the wint_t value returned by getwchar() is stored into a variable of
40 type wchar_t and then compared against the wint_t macro WEOF, the
41 result may be incorrect. Only the wint_t type is guaranteed to be able
42 to represent any wide character and WEOF.
