fgetws






fgetws − read a wide‐character string from a FILE stream


#include<wchar.h>

     , int wchar_t *fgetws(wchar_t *ws

The function is the wide‐character equivalent of the
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

The function, if successful, returns ws.  If end of stream
was already reached or if an error occurred, it returns
NULL.

The behavior of depends on the LC_CTYPE category of the
current locale.

     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.
