The EnumSnapshotAgentSessionDetails2 method differs from the EnumSnapshotAgentSessionDetails method by including the lEstimatedNumRecords parameter, which allows an application to pass an estimated number of QueryResults rows. This allows the application to avoid the performance overhead associated with repeatedly allocating and freeing memory.
To increase the accuracy of the estimated number of QueryResults rows, an application can pass the value of the action_count column returned by the EnumSnapshotAgentSessions or EnumSnapshotAgentSessions2 method to the lEstimatedNumRecords parameter.
