        _In_ size_t bufferSize,
        _Out_opt_ size_t* written);

• buffer: Pointer to buffer
• bufferSize: Buffer size
• written: Total number of characters written

This API is experimental and may have breaking change later. When size of the buffer is unknown, buffer argument can be nullptr. In that case, written argument will return the length needed.
