void edmiFreeQueryResult(SdaiQueryResult queryResult);

Releases the virtual memory allocated by the edmiExecuteQuery and edmiExecuteQueryBN operations. The EDMinterface is allocating the required virtual memory for the result from an EDMquery. It is the calling applications responsibility to release this virtual memory when it is not longer needed to avoid "out of virtual memory" and avoid memory leakage.
