| <p><a name="index-annotations-for-running-programs-2158"></a> |
| <a name="index-starting-annotation-2159"></a><a name="index-stopping-annotation-2160"></a>When the program starts executing due to a <span class="sc">gdb</span> command such as |
| <code>step</code> or <code>continue</code>, |
| |
| <pre class="smallexample"> ^Z^Zstarting |
| </pre> |
| <p>is output. When the program stops, |
| |
| <pre class="smallexample"> ^Z^Zstopped |
| </pre> |
| <p>is output. Before the <code>stopped</code> annotation, a variety of |
| annotations describe how the program stopped. |
| |
| |
| <a name="index-exited-annotation-2161"></a> |
| <dl><dt><code>^Z^Zexited </code><var>exit-status</var><dd>The program exited, and <var>exit-status</var> is the exit status (zero for |
| successful exit, otherwise nonzero). |

| </pre> |
| <p class="noindent">where <var>name</var> is the name of the signal, such as <code>SIGILL</code> or |
| <code>SIGSEGV</code>, and <var>string</var> is the explanation of the signal, such |
| as <code>Illegal Instruction</code> or <code>Segmentation fault</code>. |
| <var>intro-text</var>, <var>middle-text</var>, and <var>end-text</var> are for the |
| user's benefit and have no particular format. |
| |
| <p><a name="index-signal-annotation-2167"></a><br><dt><code>^Z^Zsignal</code><dd>The syntax of this annotation is just like <code>signalled</code>, but <span class="sc">gdb</span> is |
| just saying that the program received the signal, not that it was |
| terminated with it. |
