xcan_suspend(9)

💤 xcan_suspend(9) — like, the suspend one

okay so bestie, we're in the Kernel API Manual (xcan_suspend(9) if you're being formal 💅) and this page is short and sweet. Let's go ✨

---

🌸 NAME 🌸

xcan_suspend — the suspend method for the driver. that's it. that's the whole vibe. she puts things to sleep 😴

---

✨ SYNOPSIS ✨

int xcan_suspend (struct device *dev );

yep, that's the whole signature. one argument, one int coming back at you 🫶

---

🎀 ARGUMENTS 🎀

• dev — the address of the device structure. like, the actual pointer to it, not a copy. she needs the address, okay? 📍

---

🦋 DESCRIPTION 🦋

Put the driver into low power mode. that's the entire description and honestly? iconic. minimal. no notes 🔥

she's a suspend method, so she does the low-power thing — that's her whole personality 💜

---

⭐ RETURN ⭐

• 0 on success 🎉
• a failure value on error 😭

ngl the manpage doesn't get more specific than "failure value" on the error case, so don't come for me — that's literally all it says 🙈
