NAME

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

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <wchar.h>

       wchar_t *fgetws(wchar_t ws[restrict .n], int n, FILE *restrict 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.

HISTORY

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.
