} | RspData |
When the Token is used for host address to host name translation, A2HData is a pointer to the DNS_ADDR_TO_HOST_DATA.
This Event will be signaled after the Status field is updated by the EFI DNS protocol driver. The type of Event must be EFI_NOTIFY_SIGNAL.
When the Token is used for a general lookup function, GLookupDATA is a pointer to the DNS_GENERAL_LOOKUP_DATA.
When the Token is used for host name to address translation, H2AData is a pointer to the DNS_HOST_TO_ADDR_DATA.
Retry number if no response received after RetryInterval. If zero, use the parameter configured through Dns.Configure() interface.
Minimum interval of retry is 2 second. If the retry interval is less than 2 seconds, then use the 2 seconds. If zero, use the parameter configured through Dns.Configure() interface.

EFI_STATUS EFI_DNS4_COMPLETION_TOKEN::Status |
Will be set to one of the following values: EFI_SUCCESS: The host name to address translation completed successfully. EFI_NOT_FOUND: No matching Resource Record (RR) is found. EFI_TIMEOUT: No DNS server reachable, or RetryCount was exhausted without response from all specified DNS servers. EFI_DEVICE_ERROR: An unexpected system or network error occurred. EFI_NO_MEDIA: There was a media error.
