When requesting the process list, the <var>annex</var> field in the
|
||
|
|
‘<samp><span class="samp">qXfer</span></samp>’ request should be ‘<samp><span class="samp">processes</span></samp>’. The returned data is
|
||
|
|
an XML document. The formal syntax of this document is defined in
|
||
|
|
<samp><span class="file">gdb/features/osdata.dtd</span></samp>.
|
||
|
|
|
||
|
|
<p>An example document is:
|
||
|
|
|
||
|
|
<pre class="smallexample"> <?xml version="1.0"?>
|
||
|
|
<!DOCTYPE target SYSTEM "osdata.dtd">
|
||
|
|
<osdata type="processes">
|
||
|
|
<item>
|
||
|
|
<column name="pid">1</column>
|
||
|
|
<column name="user">root</column>
|
||
|
|
<column name="command">/sbin/init</column>
|
||
|
|
<column name="cores">1,2,3</column>
|
||
|
|
</item>
|
||
|
|
</osdata>
|
||
|
|
</pre>
|
||
|
|
<p>Each item should include a column whose name is ‘<samp><span class="samp">pid</span></samp>’. The value
|
||
|
|
of that column should identify the process on the target. The
|
||
|
|
‘<samp><span class="samp">user</span></samp>’ and ‘<samp><span class="samp">command</span></samp>’ columns are optional, and will be
|
||
|
|
displayed by <span class="sc">gdb</span>. The ‘<samp><span class="samp">cores</span></samp>’ column, if present,
|
||
|
|
should contain a comma-separated list of cores that this process
|
||
|
|
is running on. Target may provide additional columns,
|
||
|
|
which <span class="sc">gdb</span> currently ignores.
