To efficiently update the list of threads and their attributes,
|
||
|
|
<span class="sc">gdb</span> issues the ‘<samp><span class="samp">qXfer:threads:read</span></samp>’ packet
|
||
|
|
(see <a href="qXfer-threads-read.html#qXfer-threads-read">qXfer threads read</a>) and obtains the XML document with
|
||
|
|
the following structure:
|
||
|
|
|
||
|
|
<pre class="smallexample"> <?xml version="1.0"?>
|
||
|
|
<threads>
|
||
|
|
<thread id="id" core="0" name="name">
|
||
|
|
... description ...
|
||
|
|
</thread>
|
||
|
|
</threads>
|
||
|
|
</pre>
|
||
|
|
<p>Each ‘<samp><span class="samp">thread</span></samp>’ element must have the ‘<samp><span class="samp">id</span></samp>’ attribute that
|
||
|
|
identifies the thread (see <a href="thread_002did-syntax.html#thread_002did-syntax">thread-id syntax</a>). The
|
||
|
|
‘<samp><span class="samp">core</span></samp>’ attribute, if present, specifies which processor core
|
||
|
|
the thread was last executing on. The ‘<samp><span class="samp">name</span></samp>’ attribute, if
|
||
|
|
present, specifies the human-readable name of the thread. The content
|
||
|
|
of the of ‘<samp><span class="samp">thread</span></samp>’ element is interpreted as human-readable
|
||
|
|
auxiliary information. The ‘<samp><span class="samp">handle</span></samp>’ attribute, if present,
|
||
|
|
is a hex encoded representation of the thread handle.
