| |
| <p>This annotation occurs right before <small>GDB</small> responds to an error. |
| </p> |
| <p>Quit and error annotations indicate that any annotations which <small>GDB</small> 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 <small>GDB</small> is immediately returning all the way |
| to the top level. |
| </p> |
| <a name="index-error_002dbegin"></a> |
| <p>A quit or error annotation may be preceded by |
| </p> |
| <div class="smallexample"> |
| <pre class="smallexample">^Z^Zerror-begin |
| </pre></div> |
| |
| <p>Any output between that and the quit or error annotation is the error |
| message. |
| </p> |
| <p>Warning messages are not yet annotated. |
