get_channel(9)

💅 get_channel(9) — from your Kernel API Manual bestie 🎀

okay so ✨ welcome to the Kernel API Manual, section 9, and today's main character is get_channel — literally just "get pointer to channel". that's it. that's the vibe. 🦋

---

✨ SYNOPSIS ✨

struct channel * get_channel (struct most_interface *iface , int channel_id );

like, you hand it two things and it hands you back a struct channel *. no cap. 🔥

---

🌸 ARGUMENTS 🌸

• iface — the interface structure 💖 this is your struct most_interface *, it's giving "who am I even talking to"
• channel_id — the channel ID 🎀 a plain old int, the literal number of the channel you're hunting for

---

👑 DESCRIPTION 👑

so what does it actually do? it traverses the channel list — like, walks the whole thing — and returns the channel that matches both the ID and the interface. matching on two things, not one, iykyk 💅

it returns a pointer to the channel on success, or NULL otherwise. yes, NULL. so please, bestie, check it before you dereference it, because that's just good manners 🙈
