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