 *        Pointer to storage for a char variable
 * @param ipv6InterfaceIdentifier_val_ptr_len_ptr
 *        Pointer to a size_t. On entry, it will contain the size (in bytes)
 *        pointed to by ipv6InterfaceIdentifier.
 *        On exit, this value should contain the data size (in bytes).
 *
 * @retval MFD_SUCCESS         : success
 * @retval MFD_SKIP            : skip this node (no value for now)
 * @retval MFD_ERROR           : Any other error
*
 * @note If you need more than (*ipv6InterfaceIdentifier_val_ptr_len_ptr) bytes of memory,
 *       allocate it using malloc() and update ipv6InterfaceIdentifier_val_ptr_ptr.
 *       <b>DO NOT</b> free the previous pointer.
 *       The MFD helper will release the memory you allocate.
 *
 * @remark If you call this function yourself, you are responsible
 *         for checking if the pointer changed, and freeing any
 *         previously allocated memory. (Not necessary if you pass
 *         in a pointer to static memory, obviously.)
