Parameters flag the trace control flags that define what information is traced.
This routine can be called by the application program. This lets the program start the trace from within the program, dynamically and selectively. The flag has the same meaning as the trace flag passed by PM upon startup. Notes Tracing is initially on when the application starts. If a trace event, such as kernel statistics or communication events, was not selected at the start of the application it cannot be enabled by this routine.
