NAME

       fgetws - read a wide-character string from a FILE stream

SYNOPSIS

       #include <wchar.h>

       wchar_t *fgetws(wchar_t *ws, int n, FILE *stream);

DESCRIPTION

       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).

RETURN VALUE

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

CONFORMING TO

       POSIX.1-2001, POSIX.1-2008, C99.

NOTES

       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.
