<h2 class="chapter">4 <code>gprof</code> Command Summary</h2>
|
|
|
|
<p>After you have a profile data file <span class="file">gmon.out</span>, 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 <span class="samp">></span>.
|
|
|
|
<p>You run <code>gprof</code> like this:
|
|
|
|
<pre class="smallexample"> gprof <var>options</var> [<var>executable-file</var> [<var>profile-data-files</var>...]] [> <var>outfile</var>]
|
|
</pre>
|
|
<p class="noindent">Here square-brackets indicate optional arguments.
|
|
|
|
<p>If you omit the executable file name, the file <span class="file">a.out</span> is used. If
|
|
you give no profile data file name, the file <span class="file">gmon.out</span> 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>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>The order of these options does not matter.
