<h2 class="chapter">17 Altering Execution</h2>
|
|
|
|
<p>Once you think you have found an error in your program, you might want to
|
|
find out for certain whether correcting the apparent error would lead to
|
|
correct results in the rest of the run. You can find the answer by
|
|
experiment, using the <small>GDB</small> features for altering execution of the
|
|
program.
|
|
</p>
|
|
<p>For example, you can store new values into variables or memory
|
|
locations, give your program a signal, restart it at a different
|
|
address, or even return prematurely from a function.
|
