<pre class="smallexample"> -ada-task-info [ <var>task-id</var> ]
|

</pre>
|

|
|
<p>Reports information about either a specific Ada task, if the
|
||
|
|
<var>task-id</var> parameter is present, or about all Ada tasks.

|
<p>The ‘<samp><span class="samp">info tasks</span></samp>’ command prints the same information
|
||
|
|
about all Ada tasks (see <a href="Ada-Tasks.html#Ada-Tasks">Ada Tasks</a>).
|
||
|
|
|
||
|
|
<h5 class="subsubheading">Result</h5>
|
||
|
|
|
||
|
|
<p>The result is a table of Ada tasks. The following columns are
|
||
|
|
defined for each Ada task:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt>‘<samp><span class="samp">current</span></samp>’<dd>This field exists only for the current thread. It has the value ‘<samp><span class="samp">*</span></samp>’.
|
||
|
|
|
||
|
|
<br><dt>‘<samp><span class="samp">id</span></samp>’<dd>The identifier that <span class="sc">gdb</span> uses to refer to the Ada task.
|
||
|
|
|
||
|
|
<br><dt>‘<samp><span class="samp">task-id</span></samp>’<dd>The identifier that the target uses to refer to the Ada task.
|
||
|
|
|
||
|
|
<br><dt>‘<samp><span class="samp">thread-id</span></samp>’<dd>The global thread identifier of the thread corresponding to the Ada
|
||
|
|
task.
|
||
|
|
|
||
|
|
<p>This field should always exist, as Ada tasks are always implemented
|
||
|
|
on top of a thread. But if <span class="sc">gdb</span> cannot find this corresponding
|
||
|
|
thread for any reason, the field is omitted.
|
||
|
|
|
||
|
|
<br><dt>‘<samp><span class="samp">parent-id</span></samp>’<dd>This field exists only when the task was created by another task.
|
||
|
|
In this case, it provides the ID of the parent task.
|
||
|
|
|
||
|
|
<br><dt>‘<samp><span class="samp">priority</span></samp>’<dd>The base priority of the task.
|
||
|
|
|
||
|
|
<br><dt>‘<samp><span class="samp">state</span></samp>’<dd>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>.
|
||
|
|
|
||
|
|
<br><dt>‘<samp><span class="samp">name</span></samp>’<dd>The name of the task.
