std::fputws

From cppreference.com
< cpplrm; | iolrm; | 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

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

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

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