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.
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. |
