<h2 class="chapter">5 Stopping and Continuing</h2>
|
||
|
|
|
||
|
|
<p>The principal purposes of using a debugger are so that you can stop your
|
||
|
|
program before it terminates; or so that, if your program runs into
|
||
|
|
trouble, you can investigate and find out why.
|
||
|
|
|
||
|
|
<p>Inside <span class="sc">gdb</span>, your program may stop for any of several reasons,
|
||
|
|
such as a signal, a breakpoint, or reaching a new line after a
|
||
|
|
<span class="sc">gdb</span> command such as <code>step</code>. You may then examine and
|
||
|
|
change variables, set new breakpoints or remove old ones, and then
|
||
|
|
continue execution. Usually, the messages shown by <span class="sc">gdb</span> provide
|
||
|
|
ample explanation of the status of your program—but you can also
|
||
|
|
explicitly request this information at any time.
