| <h4 class="subheading">The <code>-ada-task-info</code> Command</h4> |
| |
| <p><a name="index-g_t_002dada_002dtask_002dinfo-3007"></a> |
| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <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. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <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. |
| |
| </dl> |
