Let's try to avoid using globals to pass values between functions where possible. Looks like your goal is just to pass this from pctl_cfg() to pctl_start() which runs right afterwards. Can we instead not just call pctl_start() from within pctl_cfg() (at the end), so that this can just be a local passed along as a parameter?
