DLPI Primitives Connection-mode Service Primitives an incoming DL_CONNECT_IND is being refused, the correlation number associated with that connect indication must be supplied. The message indicates the reason for the disconnection. Format The message consists of one M_PROTO message block containing the structure shown below. typedef struct { ulong dl_primitive; ulong dl_reason; ulong dl_correlation; } dl_disconnect_req_t; Parameters dl_primitive DL_DISCONNECT_REQ dl_reason reason for the disconnection. DL_DISC_NORMAL_CONDITION: normal release of a data link connection. DL_DISC_ABNORMAL_CONDITION: abnormal release of a data link connection. DL_CONREJ_PERMANENT_COND: a permanent condition caused the rejection of a connect request. DL_CONREJ_TRANSIENT_COND: a transient condition caused the rejection of a connect request. DL_UNSPECIFIED: reason unspecified dl_correlation if non-zero, conveys the correlation number that was contained in the DL_CONNECT_IND being rejected. This value permits the DLS provider to associate the primitive with the proper DL_CONNECT_IND when rejecting an incoming connection. If disconnect request is releasing a connection that is already established, or is aborting a previously sent DL_CONNECT_REQ, the value of dl_correlation should be zero. State 140 Chapter 2
