DL_XID_IND (dl_xid_ind_t) - conveys an XID DLSDU from the DLS Provider to the DLS User.
The message consists of one M_PROTO message block, followed by zero or more M_DATA blocks containing zero or more bytes of data. The message structure is as follows:
typedef struct { t_uscalar_t dl_primitive; t_uscalar_t dl_flag; t_uscalar_t dl_dest_addr_length; t_uscalar_t dl_dest_addr_offset; t_uscalar_t dl_src_addr_length; t_uscalar_t dl_src_addr_offset; } dl_xid_ind_t;
- dl_primitive
conveys DL_XID_IND
- dl_flag
conveys the flag values associated with the received XID frame.
- DL_POLL_FINAL
indicates if the received xid frame had the poll/final bit set.
- dl_dest_addr_length
conveys the length of the DLSAP address of the destination DLS User. If the destination user is implemented using DLPI, this address is the full DLSAP address returned on the DL_BIND_ACK.
- dl_dest_addr_offset
conveys the offset from the beginning of the M_PROTO message block where the destination DLSAP address begins.
- dl_src_addr_length
conveys the length of the source DLSAP address. If the source user is implemented using DLPI, this address if the full DLSAP address returned on the DL_BIND_ACK.
- dl_src_addr_offset
conveys the offset from the beginning of the M_PROTO message block where the source DLSAP address begins.
The message is valid in state DL_IDLE and DL_DATAXFER.
The resulting state is unchanged.
The DLS User must respond with a DL_XID_RES.
