 * Purpose: parse runtime control option target parameter                     *

 *                                                                            *

 * Parameters: opt        - [IN] the runtime control option                   *

 *             len        - [IN] the runtime control option length without    *

 *                               parameter                                    *

 *             size_total - [IN] total number of parsed bytes (optional)      *

 *             j          - [OUT] the runtime control option result           *

 *             error      - [OUT] error message                               *

 * Return value: SUCCEED - the runtime control option was processed           *

 *               FAIL    - otherwise                                          *
