示例1: RTMEDIA_Read
/**
* \brief Wrapper for the Media Read function.
* This wrapper protects from simultanoeous access to the same media
* \param pRtMedia Pointer to a RtMedia instance
* \param address Address at which to write
* \param data Pointer to the data to write
* \param length Size of the data buffer
* \param callback Optional pointer to a callback function to invoke when
* the write operation terminates
* \param argument Optional argument for the callback function
* \return Operation result code
