<span>How does it work?</span>

</h2>
|

</doc-anchor-target>
|
||
<p>pocketpy provides a C-API <code v-pre>py_debugger_waitforattach</code>,
|
||
which starts a debug server and waits for the VSCode extension to attach.
|
||
When the debugger is attached, the program will continue to run.</p>
|
||
<ul>
|
||
<li>If you are using pocketpy's standalone executable <code v-pre>main.exe</code>, you can pass <code v-pre>--debug</code> flag to it. This will automatically call <code v-pre>py_debugger_waitforattach("127.0.0.1", 6110)</code> before running your program.</li>
|
||
<li>If you are embedding pocketpy as a library, you need to call <code v-pre>py_debugger_waitforattach</code> manually in your C/C++ code.</li>
|
||
</ul>
