<dt><code>-e </code><var>function_name</var><dd>The ‘<samp><span class="samp">-e </span><var>function</var></samp>’ option tells <code>gprof</code> to not print
|
||
|
|
information about the function <var>function_name</var> (and its
|
||
|
|
children<small class="dots">...</small>) in the call graph. The function will still be listed
|
||
|
|
as a child of any functions that call it, but its index number will be
|
||
|
|
shown as ‘<samp><span class="samp">[not printed]</span></samp>’. More than one ‘<samp><span class="samp">-e</span></samp>’ option may be
|
||
|
|
given; only one <var>function_name</var> may be indicated with each ‘<samp><span class="samp">-e</span></samp>’
|
||
|
|
option.
|

|
|

|
|
<br><dt><code>-E </code><var>function_name</var><dd>The <code>-E </code><var>function</var> option works like the <code>-e</code> option, but
|
||
|
|
time spent in the function (and children who were not called from
|
||
|
|
anywhere else), will not be used to compute the percentages-of-time for
|
||
|
|
the call graph. More than one ‘<samp><span class="samp">-E</span></samp>’ option may be given; only one
|
||
|
|
<var>function_name</var> may be indicated with each ‘<samp><span class="samp">-E</span></samp>’ option.
|

|
|
|
||
|
|
<br><dt><code>-f </code><var>function_name</var><dd>The ‘<samp><span class="samp">-f </span><var>function</var></samp>’ option causes <code>gprof</code> to limit the
|
||
|
|
call graph to the function <var>function_name</var> and its children (and
|
||
|
|
their children<small class="dots">...</small>). More than one ‘<samp><span class="samp">-f</span></samp>’ option may be given;
|
||
|
|
only one <var>function_name</var> may be indicated with each ‘<samp><span class="samp">-f</span></samp>’
|

|
|
option.

|
|
|
||
|
|
<br><dt><code>-F </code><var>function_name</var><dd>The ‘<samp><span class="samp">-F </span><var>function</var></samp>’ option works like the <code>-f</code> option, but
|
||
|
|
only time spent in the function and its children (and their
|
||
|
|
children<small class="dots">...</small>) will be used to determine total-time and
|
||
|
|
percentages-of-time for the call graph. More than one ‘<samp><span class="samp">-F</span></samp>’ option
|
||
|
|
may be given; only one <var>function_name</var> may be indicated with each
|
||
|
|
‘<samp><span class="samp">-F</span></samp>’ option. The ‘<samp><span class="samp">-F</span></samp>’ option overrides the ‘<samp><span class="samp">-E</span></samp>’ option.

<p>Note that only one function can be specified with each <code>-e</code>,
|
||
|
|
<code>-E</code>, <code>-f</code> or <code>-F</code> option. To specify more than one
|
||
|
|
function, use multiple options. For example, this command:
|
||
|
|
|
||
|
|
<pre class="example"> gprof -e boring -f foo -f bar myprogram > gprof.output
|
||
|
|
</pre>
|
||
|
|
<p class="noindent">lists in the call graph all functions that were reached from either
|
||
|
|
<code>foo</code> or <code>bar</code> and were not reachable from <code>boring</code>.
