lr_stop_transaction_instance（）
終止由其句柄指定的事務實例的報告統計信息。
double lr_stop_transaction_instance（long parent_handle）;
參數說明：
parent_handle：唯一的事務句柄。
調用lr_stop_transaction_instance後，由“get”事務函數返回的統計信息只反映直到調用的數據，直到調用lr_resume_transaction_instance。指定的事務實例必須已使用lr_start_transaction_instance打開。
但是，數據收集不會中斷。在調用lr_resume_transaction_instance之後，“get”函數自事務實例開始後返回所有數據。此外，分析測試時的最終結果將反映總值，包括交易停止和恢復之間的期間。
如果未調用lr_resume_transaction_instance，則最終結果僅反映到調用lr_stop_transaction_instance之前的統計信息。
parent_handle是從對創建實例的lr_start_transaction_instance的調用返回的值。
lr_stop_transaction_instance和lr_resume_transaction_instance可用於有條件地收集有關開始或所有事務的信息。
請注意，在調用lr_stop_transaction_instance時，您將無法區分迭代之間的分析，也可能無法區分迭代。
要更靈活地有條件地記錄事務時間，請參閱lr_start_sub_transaction，lr_set_transaction和lr_start_timer。
lr_stop_transaction_instance返回實例的持續時間（以秒爲單位）。
