🎀 viortc_clock_cap(9) 🎀

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for viortc_clock_cap, and honestly? she's a little wrapper function doing her thing and we're gonna appreciate her. 💅

---

✨ NAME ✨

viortc_clock_cap — the VIRTIO_RTC_REQ_CLOCK_CAP wrapper. that's it, that's her whole job, girl is a wrapper and she's thriving 🫶

---

🌸 SYNOPSIS 🌸

int viortc_clock_cap (struct viortc_dev *viortc , u16 vio_clk_id , u8
*type , u8 *leap_second_smearing , u8 *flags );

---

💖 ARGUMENTS 💖

okay so let's meet the cast 👑

• viortc — the device data. this is, like, her whole world.
• vio_clk_id — the virtio_rtc clock id. yes it's a u16, no we don't ask questions.
• type — the virtio_rtc clock type.
• leap_second_smearing — the virtio_rtc smearing variant. iconic name, no notes, it's giving astronomy degree 🪐
• flags — struct virtio_rtc_resp_clock_cap.flags. literally the flags field of that struct, exactly, copy-paste that into your brain.

🦋 CONTEXT 🦋

Process context. that's the whole vibe. no softirq shenanigans, no interrupt energy, just process context, slay ✨
