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.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

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.
