heci_hcsr_read(9)

💖 heci_hcsr_read(9) 💖

okay bestie, so this is a page from the Kernel API Manual (section 9, the kernel-functions girlies ✨), and honestly? she's short, she's sweet, she's giving minimalist icon. let's get into it 💅

---

✨ NAME ✨

heci_hcsr_read — reads 32bit data from the host CSR</p> 🎀

that's it. that's the whole vibe. thirty-two bits of host CSR data, served fresh 🍓

---

🦋 SYNOPSIS 🦋

u32 heci_hcsr_read (const struct issei_device *idev );

literally that's the whole call. copy it exactly, no cap, don't be out here "fixing" the spacing 🙈

---

🌸 ARGUMENTS 🌸

• idev — the device structure 💜 that's your device, bestie, hand her over and let her cook.

---

👑 RETURN 👑

H_CSR register value</p> — as a u32, obviously 💅 so you get the H_CSR register value back, typed as a 32bit unsigned int. she ate and left no crumbs 🔥
