FPUTWS(3)                                                               Linux Programmer's Manual                                                              FPUTWS(3)

NAME
       fputws - write a wide-character string to a FILE stream

SYNOPSIS
       #include <wchar.h>

       int fputws(const wchar_t *restrict ws, FILE *restrict stream);

DESCRIPTION
       The fputws() function is the wide-character equivalent of the fputs(3) function.  It writes the wide-character string starting at ws, up to but not including the
       terminating null wide character (L'\0'), to stream.

       For a nonlocking counterpart, see unlocked_stdio(3).

RETURN VALUE
       The fputws() function returns a nonnegative integer if the operation was successful, or -1 to indicate an error.

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

NOTES
       The behavior of fputws() 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 fputws() will actually write the  multibyte  string  corre‐
       sponding to the wide-character string ws.
