fputws(3) Library Functions Manual fputws(3)
NAME
fputws - write a wide-character string to a FILE stream
LIBRARY
Standard C library (libc, -lc)
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).

STANDARDS
C11, POSIX.1-2008.
HISTORY
POSIX.1-2001, 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 corresponding to the wide-character string ws.
