fgetws - read a wide-character string from a FILE stream
#include <wchar.h>wchar_t *fgetws(wchar_t *ws, int n, FILE *stream);
function is the wide-character equivalent
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.
function, if successful, returns ws.
If end of stream
was already reached or if an error occurred, it returns NULL.
The behavior of

category of the
In the absence of additional information passed to the
call, it is
reasonable to expect that
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.
