Summary report

You can obtain a summary of profiling data by invoking lprof with the -s option:

$ lprof -s -c sample.cnt

Because a source listing is not produced by lprof -s, the -I option need not be specified. The summary reports the percentage of lines of code that were executed for each function in the profiled program, as shown in ``Example of lprof -s Output''.

Example of lprof -s Output

To obtain both a source listing report and a summary report, you can invoke lprof with the -s and -p options. As an exercise, divide the sample.c file into four parts:

1. sample.c containing main()

2. sample1.c containing sub1()

3. sample2.c containing sub2()

4. sample3.c containing sub3()

   lprof -p -s -c sample.cnt -r sample3.c
