💅 tuner_g_frequency(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this lil page is all about tuner_g_frequency, which is, like, literally the function that gets you the tuned frequency for the tuner. yes that tuner. iykyk 🎀

✨ NAME ✨

tuner_g_frequency — Get the tuned frequency for the tuner 🌸

---

🦋 SYNOPSIS 🦋

int tuner_g_frequency (struct v4l2_subdev *sd , struct v4l2_frequency *f
);

like… that's the whole signature, no notes 💅

---

💖 ARGUMENTS 💖

• sd — pointer to struct v4l2_subdev. that's your subdev bestie 🫶
• f — pointer to struct v4l2_frequency. this is the one that's gonna get filled in, main character energy fr ✨

---

🧚 DESCRIPTION 🧚

so at return — like, when the call comes back — the structure f will be filled with the tuner frequency, but only if the tuner matches f->type. conditional slay, no cap 💀

---

⭐ NOTE ⭐

f->type should be initialized before calling it!! 🙈

and like, no stress, because this is done by either video_ioctl2 or by the bridge driver. so it's handled, but bestie… it's still your vibe check to know about it 👑
