dvb_ca_en502...oll_cam_gone(9)

💖 NAME 💖

dvb_ca_en50221_poll_cam_gone — bestie, this one literally just polls to check if the CAM has dipped 👋 like it's asking "is she still there? 👀"

So this page lives in the Kernel API Manual (yes, the whole thing is a kernel API moment, we love that for it) ✨

---

🌸 SYNOPSIS 🌸

int dvb_ca_en50221_poll_cam_gone (struct dvb_ca_private *ca , int slot );

okay so it takes your CA instance and a slot, that's the whole vibe 💅

---

🦋 ARGUMENTS 🦋

• ca — your CA instance. the main character of this function tbh 🫶
• slot — the slot to process. that's the one we're checking on 🔍

and then there's the return situation, which got squished onto the end of slot in the original (no cap, it's just sitting there 😭) — so here it is with the breathing room it deserves:

return:: 0 .. no change
          1 .. CAM state changed

so like — 0 means no change, 1 means the CAM state changed. those are your only two options, periodt 💀
