| <dd><p>To exit <small>GDB</small>, use the <code>quit</code> command (abbreviated |
| <code>q</code>), or type an end-of-file character (usually <kbd>Ctrl-d</kbd>). If you |
| do not supply <var>expression</var>, <small>GDB</small> will terminate normally; |
| otherwise it will terminate using the result of <var>expression</var> as the |
| error code. |
| </p></dd> |
| </dl> |
| |
| <a name="index-interrupt"></a> |
| <p>An interrupt (often <kbd>Ctrl-c</kbd>) does not exit from <small>GDB</small>, but rather |
| terminates the action of any <small>GDB</small> command that is in progress and |
| returns to <small>GDB</small> command level. It is safe to type the interrupt |
| character at any time because <small>GDB</small> does not allow it to take effect |
| until a time when it is safe. |
| </p> |
| <p>If you have been using <small>GDB</small> to control an attached process or |
| device, you can release it with the <code>detach</code> command |
| (see <a href="Attach.html#Attach">Debugging an Already-running Process</a>). |
