Error Details

This error code is returned by various Windows API functions when a DNS query operation has been initiated but has not yet yielded a result. It does not indicate an error condition; rather, it serves as an informational message to inform developers or applications that the request is still being processed.

Usage Context

Developer Interpretation

When the DNS_REQUEST_PENDING error is returned, it should be interpreted as an indication that the DNS query operation has not yet completed and that a response will eventually be provided. Developers should handle this status by waiting for the completion of the request or by implementing appropriate timeout mechanisms to avoid indefinite blocking.
