) |
Used by the Client to submit its SoftwareCertificates to the Server for validation and to specify the identity of the user associated with the Session. This Service request shall be issued by the Client before it issues any other Service request after CreateSession. Failure to do so shall cause the Server to close the Session.

void Service_Browse | ( | UA_Server * | server, |
UA_Session * | session, | ||
const UA_BrowseRequest * | request, | ||
UA_BrowseResponse * | response | ||
) |
Used to discover the References of a specified Node. The browse can be further limited by the use of a View. This Browse Service also supports a primitive filtering capability.
void Service_BrowseNext | ( | UA_Server * | server, |
UA_Session * | session, | ||
const UA_BrowseNextRequest * | request, | ||
UA_BrowseNextResponse * | response | ||
