The xpxGetInstanceReferences function returns the instanceId of the instances that have a relation to the specified instance instanceId. The referencing instances is indexed from 1 and upwards such that it is possible to retrieve the referencing instances in several consecutive calls if that is wanted because of space limitation or convenience. The argument indexOfFirstReference (starting from one) specifies the index of the first instance to return. The argument maxReferences specifies the maximum instanceIds to return in one call, the argument actualReferencesRead returns the actual number of instanceIds returned in the argument referencingInstances.
