|

|
|

|
<p><a name="index-annotations-1"></a>
|
||
|
|
To produce obsolete level two annotations, start <span class="sc">gdb</span> with the
|
||
|
|
<code>--annotate=2</code> option.
|
||
|
|
|
||
|
|
<p>Annotations start with a newline character, two ‘<samp><span class="samp">control-z</span></samp>’
|
||
|
|
characters, and the name of the annotation. If there is no additional
|
||
|
|
information associated with this annotation, the name of the annotation
|
||
|
|
is followed immediately by a newline. If there is additional
|
||
|
|
information, the name of the annotation is followed by a space, the
|
||
|
|
additional information, and a newline. The additional information
|
||
|
|
cannot contain newline characters.
|
||
|
|
|
||
|
|
<p>Any output not beginning with a newline and two ‘<samp><span class="samp">control-z</span></samp>’
|
||
|
|
characters denotes literal output from <span class="sc">gdb</span>. Currently there is
|
||
|
|
no need for <span class="sc">gdb</span> to output a newline followed by two
|
||
|
|
‘<samp><span class="samp">control-z</span></samp>’ characters, but if there was such a need, the
|
||
|
|
annotations could be extended with an ‘<samp><span class="samp">escape</span></samp>’ annotation which
|
||
|
|
means those three characters as output.
|
||
|
|
|
||
|
|
<p>A simple example of starting up <span class="sc">gdb</span> with annotations is:
|
||
|
|
|
||
|
|
<pre class="smallexample"> $ gdb --annotate=2
