  18 <h4 class="subsection">Simple Examples of <small>GDB/MI</small> Interaction</h4>
  19
  20    <p>This subsection presents several simple examples of interaction using
  21 the <small>GDB/MI</small> interface.  In these examples, <code>-&gt;</code> means that the
  22 following line is passed to <small>GDB/MI</small> as input, while <code>&lt;-</code> means
  23 the output received from <small>GDB/MI</small>.

  25 <h5 class="subsubheading">Target Stop</h5>
  26
  27    <p>Here's an example of stopping the inferior process:
  28
  29 <pre class="example">     -&gt; -stop
  30      &lt;- (gdb)
  31      </pre>
  32
  33 <p>and later:
  34
  35 <pre class="example">     &lt;- *stop,reason="stop",address="0x123",source="a.c:123"
  36      &lt;- (gdb)
  37      </pre>
  38
  39 <h5 class="subsubheading">Simple CLI Command</h5>
  40
  41    <p>Here's an example of a simple CLI command being passed through
  42 <small>GDB/MI</small> and on to the CLI.
  43
  44 <pre class="example">     -&gt; print 1+2
  45      &lt;- ~3\n
  46      &lt;- (gdb)
  47      </pre>
  48
  49 <h5 class="subsubheading">Command With Side Effects</h5>
  50
  51 <pre class="example">     -&gt; -symbol-file xyz.exe
  52      &lt;- *breakpoint,nr="3",address="0x123",source="a.c:123"
  53      &lt;- (gdb)
  54      </pre>
  55
  56 <h5 class="subsubheading">A Bad Command</h5>
  57
  58    <p>Here's what happens if you pass a non-existent command:
  59
  60 <pre class="example">     -&gt; -rubbish
  61      &lt;- error,"Rubbish not found"
  62      &lt;- (gdb)
  63      </pre>
