The EnumMergeAgentSessions2 method differs from the EnumMergeAgentSessions 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.
