DLPI Primitives Primitives to Handle XID and TEST Operations DL_XID_REQ dl_flag flag values for the response as follows: DL_POLL_FINAL indicates status of the poll/final bit in the xid frame. dl_dest_addr_length 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 offset from the beginning of the M_PROTO message block where the destination DLSAP address begins. State The message is valid in states DL_IDLE and DL_DATAXFER. New State The resulting state is unchanged. Response On an invalid XID request, a DL_ERROR_ACK is issued to the user. If the remote side responds to the XID request, a DL_XID_CON will be sent to the user. It is recommended that the DLS user use a timeout procedure on an XID_REQ. The timeout may be used if the remote side does not respond to the XID request. Reasons for Failure DL_BADDATA The amount of data in the current DLSDU exceeded the DLS provider's DLSDU limit. DL_XIDAUTO Previous bind request specified provider would handle XID. DL_OUTSTATE Primitive was issued from an invalid state. DL_BADADDR 154 Chapter 2
