29 <!-- Internal events are only to be used during development, i.e. temporary time measurements, without the need
30 to modify .jfc files etc. Code that commits an internal event should NEVER be checked in.

32 Example usage:
33
34 #include "jfr/jfrEvents.hpp"
35
36 void foo() {
37 EventDuration event;
38 bar();
39 baz();
40 event.commit();

45 ...
46 $ jfr print dump.jfr

49 try (var rf = new RecordingFile(Path.of("dump.jfr)) {
50 while (rf.hasMoreEvents()) {
51 RecordedEvent e = rf.readEvent();
