Application Profiling (1 hour)

Prerequisites: None

Learn how to use the application profiler in the QNX Momentics development suite to profile a single process. Using the profiler, you can pinpoint which parts of your code are consuming the most CPU, at both the function level and the source-line level. You can then use that information to make your code more efficient. Both live and postmortem profiling are covered.
