Write \a len bytes to \a buffer starting \a offset. \a offset must be taken modulo \a size and len should be smaller than \a size.
\param rbuf a spa_ringbuffer \param buffer memory to write to \param size the size of \a buffer \param offset offset in \a buffer to write to \param data source memory \param len number of bytes to write
