EdmiError edmiRemoteGetClientNames (SdaiServerContext serverContextId,
SdaiClientId clientId,
SdaiString *hostName,
SdaiString *clientName,
SdaiInvocationId *edmiInvocationId);
|
Returns the client name and the name of the host that runs a thick EDMclient process identified by its clientId. The clientIds represent thick EDMclient processes that are statefully connected to an EDMdatabaseServer. Such processes may be the EDMapplicationServer processes of the EDMserver or any other application that is connected to the EDMserver by means of an embedded thick EDMclient.
