Extending process_logout()

[digitalstudio]

Hi.

I need to add a bit of extra functionality after process_logout() is called. I've looked into the code and found the following line:

($hook = vBulletinHook::fetch_hook('logout_process')) ? eval($hook) : false;

Therefore, I assume I can write some sort of plugin (containing my custom code) that calls the logout_process hook. Is this assumption correct? And if so, how would I go about it?

Thanks.
