C programmer's productivity tools

Summary option

You can obtain a summary report of the profile data by using the -s option:

   $ lprof -s -c sample.cnt

Because a source listing is not produced with lprof -s, the -r and -I options do not need to be specified: lprof needs only to find the data file. The following example shows output produced with the -s option:
