It is safe to type the interrupt 66character at any time because <span class="sc">gdb</span> does not allow it to take effect 67until a time when it is safe. 68 69 <p>If you have been using <span class="sc">gdb</span> to control an attached process or 70device, you can release it with the <code>detach</code> command 71(see <a href="Attach.html#Attach">Debugging an Already-running Process</a>). 72 73 </body></html> 74 75
