- * discarded once the remaining bytes has been read; the user is responsible for manually
- * discarding the last packet from the host via the \ref Endpoint_ClearOUT() macro.
- *
- * If the BytesProcessed parameter is \c NULL, the entire stream transfer is attempted at once,
- * failing or succeeding as a single unit. If the BytesProcessed parameter points to a valid
- * storage location, the transfer will instead be performed as a series of chunks. Each time
- * the endpoint bank becomes empty while there is still data to process (and after the current
- * packet has been acknowledged) the BytesProcessed location will be updated with the total number
- * of bytes processed in the stream, and the function will exit with an error code of
- * \ref ENDPOINT_RWSTREAM_IncompleteTransfer. This allows for any abort checking to be performed
- * in the user code - to continue the transfer, call the function again with identical parameters
- * and it will resume until the BytesProcessed value reaches the total transfer length.

- * discarding fully read packets from the host as needed. The last packet is not automatically
- * discarded once the remaining bytes has been read; the user is responsible for manually
- * discarding the last packet from the host via the \ref Endpoint_ClearOUT() macro.
- *
- * If the BytesProcessed parameter is \c NULL, the entire stream transfer is attempted at once,
- * failing or succeeding as a single unit. If the BytesProcessed parameter points to a valid
- * storage location, the transfer will instead be performed as a series of chunks. Each time
- * the endpoint bank becomes empty while there is still data to process (and after the current
- * packet has been acknowledged) the BytesProcessed location will be updated with the total number
- * of bytes processed in the stream, and the function will exit with an error code of
- * \ref ENDPOINT_RWSTREAM_IncompleteTransfer. This allows for any abort checking to be performed
- * in the user code - to continue the transfer, call the function again with identical parameters
- * and it will resume until the BytesProcessed value reaches the total transfer length.
- *
- * <b>Single Stream Transfer Example:</b>
- * \code
- * uint8_t ErrorCode;
- *
- * if ((ErrorCode = Endpoint_Discard_Stream(512, NULL)) != ENDPOINT_RWSTREAM_NoError)
- * {
- * // Stream failed to complete - check ErrorCode here
- * }
- * \endcode
- *
- * <b>Partial Stream Transfers Example:</b>
- * \code
- * uint8_t ErrorCode;
- * uint16_t BytesProcessed;
- *
- * BytesProcessed = 0;
- * while ((ErrorCode = Endpoint_Discard_Stream(512, &BytesProcessed)) == ENDPOINT_RWSTREAM_IncompleteTransfer)
- * {
- * // Stream not yet complete - do other actions here, abort if required
- * }
- *
- * if (ErrorCode != ENDPOINT_RWSTREAM_NoError)
- * {
- * // Stream failed to complete - check ErrorCode here
- * }
- * \endcode

- * discarding fully read packets from the host as needed. The last packet is not automatically
- * discarded once the remaining bytes has been read; the user is responsible for manually
- * discarding the last packet from the host via the \ref Endpoint_ClearOUT() macro.
- *
- * If the BytesProcessed parameter is \c NULL, the entire stream transfer is attempted at once,
- * failing or succeeding as a single unit. If the BytesProcessed parameter points to a valid
- * storage location, the transfer will instead be performed as a series of chunks. Each time
- * the endpoint bank becomes empty while there is still data to process (and after the current
- * packet has been acknowledged) the BytesProcessed location will be updated with the total number
- * of bytes processed in the stream, and the function will exit with an error code of
- * \ref ENDPOINT_RWSTREAM_IncompleteTransfer. This allows for any abort checking to be performed
- * in the user code - to continue the transfer, call the function again with identical parameters
- * and it will resume until the BytesProcessed value reaches the total transfer length.
- *
- * <b>Single Stream Transfer Example:</b>
- * \code
- * uint8_t ErrorCode;
- *
- * if ((ErrorCode = Endpoint_Discard_Stream(512, NULL)) != ENDPOINT_RWSTREAM_NoError)
