/* @brief Protect an APDU with Secure Messaging
*
* If secure messaging (SM) is activated in \a sctx and \a apdu is not already
* SM protected, \a apdu is processed with the following steps:
* \li call to \a sctx->pre_transmit
* \li encrypt \a apdu calling \a sctx->encrypt
* \li authenticate \a apdu calling \a sctx->authenticate
* \li copy the SM protected data to \a sm_apdu
*
* Data for authentication or encryption is always padded before the callback
* functions are called
*
* @param[in] card
* @param[in] apdu
* @param[in,out] sm_apdu

* @return \c SC_SUCCESS or error code if an error occurred
