EdmiError edmiRemoteGetInstanceType(SdaiServerContext serverContextId,
SdaiInstance instance,
SdaiEntity *entityId,
SdaiString *instTypeName,
SdaiInvocationId *edmiInvocationId);
|
Return the type of the instance identified by the instanceId given in the argument <instance>. The instance type is returned as an entityID that uniquely identifies the entity definition instance in the remote EDMdatabase
...
that defines the actual entity, i.e. the actual instance type.
