<p>A command is provided to list all Ada exceptions:
|
||
|
|
</p>
|
||
|
|
<dl compact="compact">
|
||
|
|
<dd><a name="index-info-exceptions"></a>

</dd>
|
||
|
|
<dt><code>info exceptions</code></dt>
|
||
|
|
<dt><code>info exceptions <var>regexp</var></code></dt>
|
||
|
|
<dd><p>The <code>info exceptions</code> command allows you to list all Ada exceptions
|
||
|
|
defined within the program being debugged, as well as their addresses.
|
||
|
|
With a regular expression, <var>regexp</var>, as argument, only those exceptions
|
||
|
|
whose names match <var>regexp</var> are listed.
|
||
|
|
</p></dd>
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<p>Below is a small example, showing how the command can be used, first
|
||
|
|
without argument, and next with a regular expression passed as an
|
||
|
|
argument.
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">(gdb) info exceptions
|

All defined Ada exceptions:
|
||
|
|

(gdb) info exceptions const.aint

All Ada exceptions matching regular expression "const.aint":
|

const.aint_global_e: 0x613b00
|

</pre></div>
|
||
|
|
|
||
|
|
<p>It is also possible to ask <small>GDB</small> to stop your program’s execution
|
||
|
|
when an exception is raised. For more details, see <a href="Set-Catchpoints.html#Set-Catchpoints">Set Catchpoints</a>.
