DLPI Primitives Connection-mode Service Primitives Response There is no immediate response to the connect request. However, if the connect request is accepted by the callee, DL_CONNECT_CON is sent to the caller, resulting in state DL_DATAXFER. If the request is erroneous, DL_ERROR_ACK is returned and the resulting state is unchanged. Reasons for Failure DL_BADADDR The destination DLSAP address was in an incorrect format or contained invalid information. DL_BADQOSPARAM The quality of service parameters contained invalid values. DL_BADQOSTYPE The quality of service structure type was not supported by the DLS provider. DL_ACCESS The DLS user did not have proper permission to use the responding stream. 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_CONNECT_IND Conveys to the local DLS user that a remote (calling) DLS user wishes to establish a data link connection.
