This section describes the functions available for the performance verification trace. The functions for the performance verification trace are as follows:

• dc_prf_get_trace_num - Report the sequential number for an acquired performance verification trace
• dc_prf_utrace_put - Acquire user-specific performance verification traces

The functions (dc_prf_~) for the performance verification trace are available on UAPs that run TP1/Server Base or TP1/LiNK. However, you must have installed TP1/Extension 1 before you can use this facility. Note that operation will be unpredictable if you run the facility while TP1/Extension 1 is not installed.
