Sets the wasted time for all open transactions.

    void lr_wasted_time( long wasteTime  );

Alphabetical Listing - C Language Utility Functions

## Return Values

No value is returned.

## Parameterization

You cannot use standard parameterization for any arguments in this function.

## Example

The following segment demonstrates the use of timers to collect wasted time, and the use of lr_wasted_time to remove that wasted time from the transactions. The output log segments below show that the effects are not reported in the Vuser log, but are reported in the Analysis session.

The segment also shows the use of lr.get_transaction_wasted_time.

    WasteTime() {
        int i, baseIter = 1000;
        char dude[1000];
        double wasteTime, actualElapsedTime;
        merc_timer_handle_t MasterT, timer;

        // Examine the total elapsed time of the action
        MasterT = lr_start_timer();

        //Start transaction
        lr_start_transaction("Demo");

        // Create some elapsed time for the transaction
        for (i=0; i< (10 * baseIter); ++i)
                sprintf(dude, "This is the way we create elapsed time artificially = %d", i);

        // Add some think time
        lr_think_time(0.5);

        // Create some wasted time and record it with timer
        timer = lr_start_timer();

        for (i=0; i< (5 * baseIter); ++i)
                sprintf(dude, "This is the way we waste time in a script = %d", i);

        wasteTime = lr_end_timer(timer);
        lr_output_message("User created waste time = %lf", wasteTime);
        lr_output_message("Before lr_wasted_time: Duration = %lf - Waste = %lf",
            lr_get_transaction_duration("Demo"),
            lr_get_transaction_wasted_time("Demo"));

        /* Convert Timer in seconds to wasted time in milliseconds and add to internally generated waste time */

        wasteTime *= 1000;
        lr_wasted_time(wasteTime);
        lr_output_message("After lr_wasted_time: Duration = %lf - Waste = %lf",
                lr_get_transaction_duration("Demo"),
                lr_get_transaction_wasted_time("Demo"));

        lr_output_message("Think time = %lf",
            lr_get_transaction_think_time("Demo"));

        lr_end_transaction("Demo", LR_AUTO);
        actualElapsedTime = lr_end_timer(MasterT);
        lr_output_message("Total Elapsed time for Action = %lf", actualElapsedTime);
        return 0;
    }

    Example: Output:
    There is no difference between the transaction duration before and after the call to lr_waste_time
    WasteTime.c(28): User created waste time = 0.031250
    WasteTime.c(32): Before lr_wasted_time: Duration = 0.609375 - Waste = 0.000000
    WasteTime.c(40): After lr_wasted_time: Duration = 0.625000 - Waste = 0.031000
    WasteTime.c(44): Think time = 0.500000
    WasteTime.c(47): Notify: Transaction Demo ended with Pass status (Duration: 0.6406 Think Time: 0.5000 Wasted Time: 0.0310).
    WasteTime.c(50): Total Elapsed time for Action = 0.640625

## Analysis: Average Response Time Raw Data

The Transaction Response Time for "Demo" is 0.61. This is the Duration from the Vuser log (0.6406) minus the Wasted Time ( 0.0310).

Transaction End Status | Transaction Father Tree path | Scenario Elapsed Time | Transaction Response Time | Transaction Name
