In the following example, the lr_get_trans_instance_think_time function gets the think time of a transaction instance, and sends it to the Output window.
long child_handle; double trans_time; int rc;
/* Start the main transaction instance. Passing 0 as the parent handle indicates that the transaction has no parent. The function return value is the handle used in other transaction instance functions. */
child_handle = lr_start_transaction_instance("ParentTransaction",0);
/*Perform the business process, represented here with a single web_url call. */ web_url("web_url", "URL=http://www.mercury.com",LAST );
// Get the transaction instance time. trans_time = lr_get_trans_instance_think_time(child_handle); lr_output_message ("Instance think time is %lf seconds.", trans_time);
