💖 sdca_add_hid_device(9) 💖

hiii bestie!! welcome to the Kernel API Manual, where we learn about the little functions that hold the whole kernel together 🫶 today's main character is sdca_add_hid_device(9) and honestly? she's giving "small but essential." like the girl who brings the aux cord to the party. no cap.

🌸 NAME 🌸

sdca_add_hid_device — create a new SDCA HID device ✨

like, literally her whole job. she spins up a brand new SDCA HID device and hands it to you, and the vibes are immaculate.

---

🦋 SYNOPSIS 🦋

int sdca_add_hid_device (struct sdca_interrupt *interrupt );

okay yes the space before the closing paren is a little quirky 😭 but that's exactly how she's written, so we're leaving it. character, not a bug. periodt.

---

🎀 ARGUMENTS 🎀

• interrupt — Pointer to the SDCA interrupt information structure. that's the one and only thing you hand her: a pointer to the SDCA interrupt info struct, and she takes it from there 💅

---

⭐ RETURN ⭐

Zero on success, and a negative error code on failure. so like — 0 means slay, we ate, everyone's happy 🎉 and anything negative means something went sideways and you should probably go read the error code instead of pretending it didn't happen 🙈

• sdca_hid_process_report(9) — the one that handles the reports, iykyk

fr fr, if you create one of these, remember to actually destroy it later. no leaving orphaned devices lying around like unread group chat messages 💀
