| |
| <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; ‘<samp><span class="samp">signal 0</span></samp>’ causes it to resume without a |
| signal. |
| |
| <p><code>signal</code> does not repeat when you press <RET> 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. |
