# std::fputws

From cppreference.com
< cpp‎ | io‎ | c

Defined in header `<cwchar>` |  |
int fputws( const wchar_t* str, std::FILE* stream ); |  |

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

The terminating null wide character from `str` is not written.

### Parameters

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

### Return value

On success, returns a non-negative value

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

### Example

Run this code

    #include <clocale>
    #include <cstdio>
    #include <cwchar>

    int main()
    {
        std::setlocale(LC_ALL, "en_US.utf8");
        int rc = std::fputws(L"御休みなさい", stdout);

        if (rc == EOF)
           std::perror("fputws()"); // POSIX requires that errno is set
    }

Output:

    御休みなさい
