                                     SdaiInstance      instance,

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.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiInstance	instance	The numeric instanceId that uniquely identifies the instance in the EDMdatabase
SdaiEntity	entityId	A variable that will receive the entityId that uniquely identifies the instance type in the remote EDMdatabase
SdaiString	instTypeName	A variable that will receive the name that has been assigned to the instance type identified by the returned entityId.
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value
