fgetws —
#include <stdio.h>
#include <wchar.h>
wchar_t *
  
  fgetws(wchar_t
    * restrict ws, int
    n, FILE * restrict
    fp);
fgetws() function reads at most one less than the
  number of characters specified by n from the given
  fp and stores them in the wide-character string
  ws. Reading stops when a newline character is found, at
  end-of-file or error. The newline, if any, is retained. If any characters are
  read and there is no error, a ‘\0’
  character is appended to end the string.
fgetws() returns
  ws. If end-of-file occurs before any characters are
  read, fgetws() returns NULL
  and the buffer contents remain unchanged. If an error occurs,
  fgetws() returns NULL and the
  buffer contents are indeterminate. The fgetws()
  function does not distinguish between end-of-file and error, and callers must
  use feof(3) and
  ferror(3) to determine which
  occurred.
EBADF]EILSEQ]The function fgetws() may also fail and
    set errno for any of the errors specified for the
    routines fflush(3),
    fstat(2),
    read(2), or
    malloc(3).
fgetws() function conforms to IEEE
  Std 1003.1-2001 (“POSIX.1”).
