<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>Any output between that and the quit or error annotation is the error
|
||
|
|
message.

<p>Warning messages are not yet annotated.
