channel_show(9)

👑 channel_show(9) — a Kernel API Manual moment

okay so bestie, welcome to the <pink>Kernel API Manual</pink> ✨ this little page is all about channel_show(9), and honestly? it's giving "tiny helper function that keeps the whole wireless mesh vibe alive" 💅

---

🌸 NAME 🌸

channel_show — the get function for the sysfs attribute channel 🎀

like, that's literally its whole job. it shows you the channel. icon behavior fr fr.

---

🦋 SYNOPSIS 🦋

ssize_t channel_show (struct device *dev , struct device_attribute *attr
, char *buf );

yes bestie, that's the whole signature — ssize_t return type and everything 💖 don't come for me about the line break, that's how she's written.

---

✨ ARGUMENTS ✨

• dev — the struct device 👑 this is your main character device, the one we're talking about.
• attr — device attributes 🌈 the attribute situation, i.e. the struct device_attribute involved here.
• buf — the buffer where data will be returned 🍓 this is where the actual answer goes, so be nice to it.

three arguments, zero drama, that's the vibe check and she passed 🫶

first up, the source file itself — the kernel file lives right here:

and now the whole friend group 😭 look at this roster, it's lowkey a group chat:
