| <h2 class="chapter">4 <code>gprof</code> Command Summary</h2> |
| |
| <p>After you have a profile data file <samp>gmon.out</samp>, you can run <code>gprof</code> |
| to interpret the information in it. The <code>gprof</code> program prints a |
| flat profile and a call graph on standard output. Typically you would |
| redirect the output of <code>gprof</code> into a file with ‘<samp>></samp>’. |
| </p> |
| <p>You run <code>gprof</code> like this: |
| </p> |
| <div class="smallexample"> |
| <pre class="smallexample">gprof <var>options</var> [<var>executable-file</var> [<var>profile-data-files</var>…]] [> <var>outfile</var>] |
| </pre></div> |
| |
| <p>Here square-brackets indicate optional arguments. |
| </p> |
| <p>If you omit the executable file name, the file <samp>a.out</samp> is used. If |
| you give no profile data file name, the file <samp>gmon.out</samp> is used. If |
| any file is not in the proper format, or if the profile data file does not |
| appear to belong to the executable file, an error message is printed. |
| </p> |
| <p>You can give more than one profile data file by entering all their names |
| after the executable file name; then the statistics in all the data files |
| are summed together. |
| </p> |
| <p>The order of these options does not matter. |
