<p>When requesting the process list, the <var>annex</var> field in the


&lsquo;<samp>qXfer</samp>&rsquo; request should be &lsquo;<samp>processes</samp>&rsquo;.  The returned data is


an XML document.  The formal syntax of this document is defined in


<samp>gdb/features/osdata.dtd</samp>.


</p>


<p>An example document is:


</p>


<div class="smallexample">


<pre class="smallexample">&lt;?xml version=&quot;1.0&quot;?&gt;


&lt;!DOCTYPE target SYSTEM &quot;osdata.dtd&quot;&gt;


&lt;osdata type=&quot;processes&quot;&gt;


  &lt;item&gt;


    &lt;column name=&quot;pid&quot;&gt;1&lt;/column&gt;


    &lt;column name=&quot;user&quot;&gt;root&lt;/column&gt;


    &lt;column name=&quot;command&quot;&gt;/sbin/init&lt;/column&gt;


    &lt;column name=&quot;cores&quot;&gt;1,2,3&lt;/column&gt;


  &lt;/item&gt;


&lt;/osdata&gt;


</pre></div>


 


<p>Each item should include a column whose name is &lsquo;<samp>pid</samp>&rsquo;.  The value


of that column should identify the process on the target.  The


&lsquo;<samp>user</samp>&rsquo; and &lsquo;<samp>command</samp>&rsquo; columns are optional, and will be


displayed by <small>GDB</small>.  The &lsquo;<samp>cores</samp>&rsquo; column, if present,


should contain a comma-separated list of cores that this process


is running on.  Target may provide additional columns,


which <small>GDB</small> currently ignores.
