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

Writes every character from the null-terminated wide string str to the output stream stream, as if by repeatedly executing fputwc.

The terminating null wide character from str is not written.

[edit] Parameters

str - null-terminated wide string to be written
stream - output stream

[edit] Return value

On success, returns a non-negative value

On failure, returns EOF and sets the error indicator (see ferror) on stream.

[edit] Example

#include <locale.h>
#include <stdio.h>
#include <wchar.h>
 
int main(void)
{
    setlocale(LC_ALL, "en_US.utf8");
    int rc = fputws(L"御休みなさい", stdout);
 
    if (rc == EOF)
       perror("fputws()"); // POSIX requires that errno is set
}

Output:

御休みなさい
