## C Language

    double lr_get_trans_instance_wasted_time (long trans_handle);

Example: lr_get_trans_instance_wasted_time | Transaction Functions

## Arguments

Name | Comments
--- | ---
trans_handle | A transaction handle.

The lr_get_trans_instance_wasted_time function returns the Wasted Time of the specified transaction until this point.

The difference between this function and lr_get_transaction_wasted_time is that with this function you specify a transaction instance by its handle. With lr_get_transaction_wasted_time, you specify an independent transaction by its name.

The trans_handle is the handle returned by the call to lr_start_transaction_instance that created the instance.

The lr_get_trans_instance_think_time function returns values greater than zero only for open transactions.

To determine other transaction statistics, such as think time and wasted time, use the appropriate Transaction Functions.

## Return Values

If this function succeeds, it returns the transaction wasted time in seconds. If it fails, it returns a negative number. If the transaction already ended or if data is not available for the specified transaction, it returns 0.

## Parameterization

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