  209. <pre class="smallexample">-list-thread-groups [ --available ] [ --recurse 1 ] [ <var>group</var> ... ]

  210. </pre></div>

  211. 

  212. <p>Lists thread groups (see <a href="Thread-groups.html#Thread-groups">Thread groups</a>).  When a single thread

  213. group is passed as the argument, lists the children of that group.

  214. When several thread group are passed, lists information about those

  215. thread groups.  Without any parameters, lists information about all

  216. top-level thread groups.

  217. </p>

  218. <p>Normally, thread groups that are being debugged are reported.

  219. With the &lsquo;<samp>--available</samp>&rsquo; option, <small>GDB</small> reports thread groups

  220. available on the target.

  221. </p>

  222. <p>The output of this command may have either a &lsquo;<samp>threads</samp>&rsquo; result or

  223. a &lsquo;<samp>groups</samp>&rsquo; result.  The &lsquo;<samp>thread</samp>&rsquo; result has a list of tuples

  224. as value, with each tuple describing a thread (see <a href="GDB_002fMI-Thread-Information.html#GDB_002fMI-Thread-Information">GDB/MI Thread Information</a>).  The &lsquo;<samp>groups</samp>&rsquo; result has a list of tuples as value,

  225. each tuple describing a thread group.  If top-level groups are

  226. requested (that is, no parameter is passed), or when several groups

  227. are passed, the output always has a &lsquo;<samp>groups</samp>&rsquo; result.  The format

  228. of the &lsquo;<samp>group</samp>&rsquo; result is described below.

  229. </p>

  230. <p>To reduce the number of roundtrips it&rsquo;s possible to list thread groups

  231. together with their children, by passing the &lsquo;<samp>--recurse</samp>&rsquo; option

  232. and the recursion depth.  Presently, only recursion depth of 1 is

  233. permitted.  If this option is present, then every reported thread group

  234. will also include its children, either as &lsquo;<samp>group</samp>&rsquo; or

  235. &lsquo;<samp>threads</samp>&rsquo; field.

  236. </p>

  237. <p>In general, any combination of option and parameters is permitted, with

  238. the following caveats:

  239. </p>

  240. <ul>

  241. <li> When a single thread group is passed, the output will typically

  242. be the &lsquo;<samp>threads</samp>&rsquo; result.  Because threads may not contain

  243. anything, the &lsquo;<samp>recurse</samp>&rsquo; option will be ignored.

  244. 

  245. </li><li> When the &lsquo;<samp>--available</samp>&rsquo; option is passed, limited information may

  246. be available.  In particular, the list of threads of a process might

  247. be inaccessible.  Further, specifying specific thread groups might

  248. not give any performance advantage over listing all thread groups.

  249. The frontend should assume that &lsquo;<samp>-list-thread-groups --available</samp>&rsquo;

  250. is always an expensive operation and cache the results.

  251. 

  252. </li></ul>

  253. 

  254. <p>The &lsquo;<samp>groups</samp>&rsquo; result is a list of tuples, where each tuple may

  255. have the following fields:

  256. </p>

  257. <dl compact="compact">

  258. <dt><code>id</code></dt>

  259. <dd><p>Identifier of the thread group.  This field is always present.

  260. The identifier is an opaque string; frontends should not try to

  261. convert it to an integer, even though it might look like one.

  262. </p>

  263. </dd>

  264. <dt><code>type</code></dt>

  265. <dd><p>The type of the thread group.  At present, only &lsquo;<samp>process</samp>&rsquo; is a

  266. valid type.

  267. </p>

  268. </dd>

  269. <dt><code>pid</code></dt>

  270. <dd><p>The target-specific process identifier.  This field is only present

  271. for thread groups of type &lsquo;<samp>process</samp>&rsquo; and only if the process exists.

  272. </p>

  273. </dd>

  274. <dt><code>exit-code</code></dt>

  275. <dd><p>The exit code of this group&rsquo;s last exited thread, formatted in octal.

  276. This field is only present for thread groups of type &lsquo;<samp>process</samp>&rsquo; and

  277. only if the process is not running.

  278. </p>

  279. </dd>

  280. <dt><code>num_children</code></dt>

  281. <dd><p>The number of children this thread group has.  This field may be

  282. absent for an available thread group.

  283. </p>

  284. </dd>

  285. <dt><code>threads</code></dt>

  286. <dd><p>This field has a list of tuples as value, each tuple describing a

  287. thread.  It may be present if the &lsquo;<samp>--recurse</samp>&rsquo; option is

  288. specified, and it&rsquo;s actually possible to obtain the threads.

  289. </p>

  290. </dd>

  291. <dt><code>cores</code></dt>

  292. <dd><p>This field is a list of integers, each identifying a core that one

  293. thread of the group is running on.  This field may be absent if

  294. such information is not available.

  295. </p>

  296. </dd>

  297. <dt><code>executable</code></dt>

  298. <dd><p>The name of the executable file that corresponds to this thread group.

  299. The field is only present for thread groups of type &lsquo;<samp>process</samp>&rsquo;,

  300. and only if there is a corresponding executable file.
