DLPI Primitives Connection-mode Service Primitives The message is valid in any of the states: DL_DATAXFER, DL_INCON_PENDING, DL_OUTCON_PENDING, DL_PROV_RESET_PENDING, DL_USER_RESET_PENDING. New State The resulting state is one of the disconnect pending states, as defined in Appendix B, Allowable Sequence of DLPI Primitives, of the DLPI 2.0 specification. Response If the disconnect is successful, DL_OK_ACK is sent to the DLS user resulting in state DL_IDLE. If the request fails, DL_ERROR_ACK is returned, and the resulting state is unchanged. Reasons for Failure DL_BADCORR The correlation number specified in this primitive did not correspond to a pending connect indication. DL_OUTSTATE The primitive was issued from an invalid state. DL_SYSERR A system error has occurred and the UNIX system error is indicated in the DL_ERROR_ACK. The UNIX error returned may be set to (not limited to) errors listed in Table 2-2 on page 71. DL_DISCONNECT_IND Informs the DLS user that the data link connection on this stream has been disconnected, or that a pending connection (either DL_CONNECT_REQ or DL_CONNECT_IND) has been aborted. This primitive indicates the origin and the cause of the disconnect. Format The message consists of one M_PROTO message block containing the structure shown below. 142 Chapter 2
