/**
 * @brief
 *	Decode a Status batch request
 *
 * @par
 *	The batch_request structure must already exist (be allocated by the
 *	caller).   It is assumed that the header fields (protocol type,
 *	protocol version, request type, and user name) have already be decoded.
 *
 * @param[in]     sock - socket handle from which to read.
 * @param[in,out] preq - pointer to the batch request structure. The following
 *		elements of the rq_ind.rq_status union are updated:
 *		rq_id     - object id, a variable length string.
 *		rq_status - the linked list of attribute structures
 *		
 * @return int
 * @retval 0 - request read and decoded successfully.
 * @retval non-zero - DIS decode error.
