The IDE lets you examine profiling information from an output file produced by an instrumented application (i.e. gmon.out). The tool provides you with all of the information collected at runtime, but in a graphical format.
Postmortem profiling supports data generated by gprof (gmon.out), the QNX profiler library (.ptrace), and the trace logger (.kev).
For more information about the gprof utility, go to www.gnu.org, see the Utilities Reference.
