hum, I dont understand.. I can se the same code in the new version:


+typedef void (*print_metric_t)(void *ctx, const char *color, const char *unit,
+                              const char *fmt, double val);
+
 void perf_stat__reset_shadow_stats(void);
 void perf_stat__update_shadow_stats(struct perf_evsel *counter, u64 *count,
                                    int cpu);
-void perf_stat__print_shadow_stats(FILE *out, struct perf_evsel *evsel,
-                                  double avg, int cpu, enum aggr_mode aggr);
+void perf_stat__print_shadow_stats(struct perf_evsel *evsel,
+                                  double avg, int cpu,
+                                  print_metric_t print_metric,
+                                  void (*new_line)(void *ctx),
+                                  void *ctx);


both:

print_metric_t print_metric
void (*new_line)(void *ctx)

are still there.. what single function call did you mean?
