Example: lr_end_sub_transaction

In the following example, a sub-transaction called "electrical_purchases," performs purchases of six electrical items. If this sub-transaction is successful, the transaction status is recorded as LR_AUTO. The default value of LR_AUTO is LR_PASS. If the purchase is unsuccessful, the value is set as LR_FAIL.

 /* Notify that a transaction is starting */
 /* Breakdown the transaction into a smaller transaction */
lr_start_sub_transaction("electrical_purchases", "purchases");
status = purchase_electrical_items(6); /* call to Server API */
 /* End transaction with operation result - pass or fail */
if (status == 0)
    lr_end_sub_transaction("electrical_purchases", LR_AUTO);
    lr_end_sub_transaction("electrical_purchases", LR_FAIL);
