<h4 class="subsection">27.5.1 <span class="sc">gdb/mi</span> Result Records</h4>
<p><a name="index-result-records-in-_0040sc_007bgdb_002fmi_007d-2968"></a><a name="index-g_t_0040sc_007bgdb_002fmi_007d_002c-result-records-2969"></a>In addition to a number of out-of-band notifications, the response to a
<span class="sc">gdb/mi</span> command includes one of the following result indications:
<a name="index-g_t_005edone-2970"></a>
<dl><dt><code>"^done" [ "," </code><var>results</var><code> ]</code><dd>The synchronous operation was successful, <var>results</var> are the return
values.
<br><dt><code>"^running"</code><dd><a name="index-g_t_005erunning-2971"></a>This result record is equivalent to &lsquo;<samp><span class="samp">^done</span></samp>&rsquo;. Historically, it
was output instead of &lsquo;<samp><span class="samp">^done</span></samp>&rsquo; if the command has resumed the
target. This behaviour is maintained for backward compatibility, but
all frontends should treat &lsquo;<samp><span class="samp">^done</span></samp>&rsquo; and &lsquo;<samp><span class="samp">^running</span></samp>&rsquo;
identically and rely on the &lsquo;<samp><span class="samp">*running</span></samp>&rsquo; output record to determine
which threads are resumed.
<br><dt><code>"^connected"</code><dd><a name="index-g_t_005econnected-2972"></a><span class="sc">gdb</span> has connected to a remote target.
<br><dt><code>"^error" "," "msg=" </code><var>c-string</var><code> [ "," "code=" </code><var>c-string</var><code> ]</code><dd><a name="index-g_t_005eerror-2973"></a>The operation failed. The <code>msg=</code><var>c-string</var> variable contains
the corresponding error message.
<p>If present, the <code>code=</code><var>c-string</var> variable provides an error
code on which consumers can rely on to detect the corresponding
error condition. At present, only one error code is defined:
<dl>
<dt>&lsquo;<samp><span class="samp">"undefined-command"</span></samp>&rsquo;<dd>Indicates that the command causing the error does not exist.
</dl>
<br><dt><code>"^exit"</code><dd><a name="index-g_t_005eexit-2974"></a><span class="sc">gdb</span> has terminated.
</dl>
