FGETWS(3) Linux Programmer's Manual FGETWS(3)
fgetws - read a wide-character string from a FILE stream
#include <wchar.h>
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
characters 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.
For an explanation of the terms used in this section, see
attributes(7).

POSIX.1-2001, POSIX.1-2008, C99.
The behavior of fgetws() depends on the LC_CTYPE category of the
current locale.
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
properly with null wide characters that may be present in the
input.
