Remarks

The ONEX_EAP_ERROR structure is used by the 802.1X module, a new wireless configuration component supported on Windows Vista and later.

Many members of the ONEX_EAP_ERROR structure correspond with similar members in the EAP_ERROR structure

The ONEX_RESULT_UPDATE_DATA contains information on a status change to 802.1X authentication. The ONEX_RESULT_UPDATE_DATA structure is returned when the NotificationSource member of the WLAN_NOTIFICATION_DATA structure is WLAN_NOTIFICATION_SOURCE_ONEX and the NotificationCode member of the WLAN_NOTIFICATION_DATA structure for received notification is OneXNotificationTypeResultUpdate. For this notification, the pData member of the WLAN_NOTIFICATION_DATA structure points to an ONEX_RESULT_UPDATE_DATA structure that contains information on the 802.1X authentication status change.

If the fEapError member in the ONEX_RESULT_UPDATE_DATA structure is set, then the eapError member of the ONEX_RESULT_UPDATE_DATA structure contains an ONEX_VARIABLE_BLOB structure with an ONEX_EAP_ERROR structure embedded starting at the dwOffset member of the ONEX_VARIABLE_BLOB.
