Function

Description

otPlatDnsStartUpstreamQuery()

Starts an upstream query transaction. - In success case (and errors represented by DNS protocol messages), the platform is expected to call `otPlatDnsUpstreamQueryDone`. - The OpenThread core may cancel a (possibly timeout) query transaction by calling `otPlatDnsCancelUpstreamQuery`, the platform must not call `otPlatDnsUpstreamQueryDone` on a cancelled transaction.

otPlatDnsCancelUpstreamQuery()

Cancels a transaction of upstream query. The platform must call `otPlatDnsUpstreamQueryDone` to release the resources.

otPlatDnsUpstreamQueryDone()

The platform calls this function to finish DNS query. The transaction will be released, so the platform must not call on the same transaction twice. This function passes the ownership of `aResponse` to OpenThread stack. Platform can pass a nullptr to close a transaction without a response.
