wchar_t *fgetws(wchar_t *ws, int n, FILE *stream);
The fgetws() function is the wide-character equivalent of the fgets(3)
function. It reads a string of at most n-1 wide characters into the
wide-character array pointed to by ws, and adds a terminating null wide
character (L'\0'). It stops reading wide characters after it has
encountered and stored a newline wide character. It also stops when
end of stream is reached.
The programmer must ensure that there is room for at least n wide char-
acters at ws.
For a nonlocking counterpart, see unlocked_stdio(3).
The fgetws() function, if successful, returns ws. If end of stream was
already reached or if an error occurred, it returns NULL.

The behavior of fgetws() depends on the LC_CTYPE category of the cur-
In the absence of additional information passed to the fopen(3) call,
it is reasonable to expect that fgetws() will actually read a multibyte
string from the stream and then convert it to a wide-character string.
This function is unreliable, because it does not permit to deal prop-
erly with null wide characters that may be present in the input.
