| <a name="index-quit-61"></a> |
| <pre class="smallexample"> ^Z^Zquit |

| <p>This annotation occurs right before <span class="sc">gdb</span> responds to an interrupt. |
| |
| <p><a name="index-error-62"></a> |
| <pre class="smallexample"> ^Z^Zerror |
| </pre> |
| <p>This annotation occurs right before <span class="sc">gdb</span> responds to an error. |
| |
| <p>Quit and error annotations indicate that any annotations which <span class="sc">gdb</span> was |
| in the middle of may end abruptly. For example, if a |
| <code>value-history-begin</code> annotation is followed by a <code>error</code>, one |
| cannot expect to receive the matching <code>value-history-end</code>. One |
| cannot expect not to receive it either, however; an error annotation |
| does not necessarily mean that <span class="sc">gdb</span> is immediately returning all the way |
| to the top level. |
| |
| <p><a name="index-error_002dbegin-63"></a>A quit or error annotation may be preceded by |
| |
| <pre class="smallexample"> ^Z^Zerror-begin |
| </pre> |
| <p>Any output between that and the quit or error annotation is the error |
| message. |
| |
| <p>Warning messages are not yet annotated. |
| <!-- If we want to change that, need to fix warning(), type_error(), --> |
| <!-- range_error(), and possibly other places. --> |
