<h3 class="section">17.3 Giving your Program a Signal</h3>

<p><a name="index-deliver-a-signal-to-a-program-929"></a>
     
<a name="index-signal-930"></a>
<dl><dt><code>signal </code><var>signal</var><dd>Resume execution where your program stopped, but immediately give it the
signal <var>signal</var>.  <var>signal</var> can be the name or the number of a
signal.  For example, on many systems <code>signal 2</code> and <code>signal
SIGINT</code> are both ways of sending an interrupt signal.

     <p>Alternatively, if <var>signal</var> is zero, continue execution without
giving a signal.  This is useful when your program stopped on account of
a signal and would ordinary see the signal when resumed with the
<code>continue</code> command; &lsquo;<samp><span class="samp">signal 0</span></samp>&rsquo; causes it to resume without a
signal.

     <p><code>signal</code> does not repeat when you press &lt;RET&gt; a second time
after executing the command. 
</dl>
   <!-- @end group -->

   <p>Invoking the <code>signal</code> command is not the same as invoking the
<code>kill</code> utility from the shell.  Sending a signal with <code>kill</code>
causes <span class="sc">gdb</span> to decide what to do with the signal depending on
the signal handling tables (see <a href="Signals.html#Signals">Signals</a>).  The <code>signal</code> command
passes the signal directly to your program.
