fgetws - read a wide character string from a FILE stream
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 widecharacter
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
The programmer must ensure that there is room for at least n wide characters
The fgetws function, if successful, returns ws. If end of stream was
already reached or if an error occurred, it returns NULL.

The behaviour of fgetws depends on the LC_CTYPE category of the current
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.
