information about the function <var>function_name</var> (and its

|
children…) 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>[not printed]</samp>’. More than one ‘<samp>-e</samp>’ option may be
|
||
|
|
given; only one <var>function_name</var> may be indicated with each ‘<samp>-e</samp>’

anywhere else), will not be used to compute the percentages-of-time for

the call graph. More than one ‘<samp>-E</samp>’ option may be given; only one

only time spent in the function and its children (and their

may be given; only one <var>function_name</var> may be indicated with each

<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:

</p>

|
<div class="example">
|
||
|
|
<pre class="example">gprof -e boring -f foo -f bar myprogram > gprof.output
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>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>.
