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.
