#include <dcprf.h>
int dc_prf_get_trace_num(trace_num, flags)
unsigned short *trace_num;
DCLONG      flags;

The function dc_prf_get_trace_num() reports the acquired sequential trace number within the process of the latest performance verification trace (prf trace) acquired before the function was called. It reports this information to the function call source.

If no performance verification trace has been acquired in the process that called the function dc_prf_get_trace_num(), the acquired sequential trace number is 0.

trace_num

Specify the leading pointer of the area in which you want to set the sequential number for an acquired performance verification trace.

flags

Specify DCNOFLAGS.
