Rolls back the changes from a failed synchronization.
void ULRollbackPartialDownload ( SQLCA * sqlca )
sqlca A pointer to the SQL Communications Area. In the C++ API, use the Sqlca.GetCA method.
When a communication error occurs during the download phase of synchronization, UltraLite can apply the downloaded changes, so that the application can resume the synchronization from the place it was interrupted. If the download changes are not needed (the user or application does not want to resume the download at this point), ULRollbackPartialDownload rolls back the failed download transaction.
