<p>Reports information about either a specific Ada task, if the

<var>task-id</var> parameter is present, or about all Ada tasks.

</p>

<a name="GDB-Command-28"></a>

<h4 class="subsubheading"><small>GDB</small> Command</h4>
|
|
<p>The ‘<samp>info tasks</samp>’ command prints the same information
|
about all Ada tasks (see <a href="Ada-Tasks.html#Ada-Tasks">Ada Tasks</a>).
|
</p>
|
<a name="Result-4"></a>
|
<h4 class="subsubheading">Result</h4>
|
|
<p>The result is a table of Ada tasks. The following columns are
|
defined for each Ada task:
|
</p>
|
<dl compact="compact">
|
<dt>‘<samp>current</samp>’</dt>
|
<dd><p>This field exists only for the current thread. It has the value ‘<samp>*</samp>’.
|
</p>
|
</dd>
|
<dt>‘<samp>id</samp>’</dt>
|
<dd><p>The identifier that <small>GDB</small> uses to refer to the Ada task.
|
</p>
|
</dd>
|
<dt>‘<samp>task-id</samp>’</dt>
|
<dd><p>The identifier that the target uses to refer to the Ada task.
|
</p>
|
</dd>
|
<dt>‘<samp>thread-id</samp>’</dt>
|
<dd><p>The global thread identifier of the thread corresponding to the Ada
|
task.
|
</p>
|
<p>This field should always exist, as Ada tasks are always implemented
|
on top of a thread. But if <small>GDB</small> cannot find this corresponding
|
thread for any reason, the field is omitted.
|
</p>
|
</dd>
|
<dt>‘<samp>parent-id</samp>’</dt>
|
<dd><p>This field exists only when the task was created by another task.
|
In this case, it provides the ID of the parent task.
|
</p>
|
</dd>
|
<dt>‘<samp>priority</samp>’</dt>
|
<dd><p>The base priority of the task.
|
</p>
|
</dd>
|
<dt>‘<samp>state</samp>’</dt>
|
<dd><p>The current state of the task. For a detailed description of the
|
possible states, see <a href="Ada-Tasks.html#Ada-Tasks">Ada Tasks</a>.
|
</p>
|
</dd>
|
<dt>‘<samp>name</samp>’</dt>
|
<dd><p>The name of the task.
