Detailed Description

EFI_DNS4_COMPLETION_TOKEN

Field Documentation

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.
