      int fwrite( const void* buffer, std::size_t size, std::size_t count, std::FILE* stream );

      Writes up to count objects from the given array buffer to the output stream stream as if by reinterepreting each object as an array of unsigned char and calling std::fputc size times for each object to write those unsigned chars into stream, in order. The file position indicator for the stream is advanced by the number of characters written.
