Expand description
Pointer is called when a DNS response is received for a browse (service instance enumeration) query.
Within this callback the user can use otDnsBrowseResponseGet{Item}()
functions along with the @p aResponse
pointer to get more info about the response.
The @p aResponse pointer can only be used within this callback and after returning from this function it will not stay valid, so the user MUST NOT retain the @p aResponse pointer for later use.
@param[in] aError The result of the DNS transaction. @param[in] aResponse A pointer to the response (it is always non-NULL). @param[in] aContext A pointer to application-specific context.
For the full list of possible values for @p aError, please see otDnsAddressCallback()
.
