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 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 L'\0' character. 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.
The fgetws function,
if successful, returns ws. If end of stream was already reached or if an
error occurred, it returns NULL.

fgetwc(3)
The behaviour of fgetws depends on the LC_CTYPE category of the current
locale.
In the absence of additional information passed to the fopen 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.
