es58x_set_realtime_diff_ns(9)

💅 es58x_set_realtime_diff_ns — the Kernel API Manual era ✨

okay so bestie, welcome to the glow-up doc for es58x_set_realtime_diff_ns(9), straight out of the Kernel API Manual. she's a little function with one job and honestly she ate 💖

---

🌸 NAME 🌸

es58x_set_realtime_diff_ns — literally calculates the difference between the clocks of the ES58X device and the kernel 🕰️✨

---

🎀 SYNOPSIS 🎀

int es58x_set_realtime_diff_ns (struct es58x_device *es58x_dev );

---

🦋 ARGUMENTS 🦋

• es58x_dev — the ES58X device itself. that's her. our main character 🫶

---

💜 DESCRIPTION 💜

okay so here's the vibe: this function requests a timestamp from the ES58X device. that's the ask. 📨

then, once the answer comes back, the timestamp difference gets set by the callback function es58x_rx_timestamp. so like — she asks, the callback handles the rest. teamwork, no cap 🤝

---

⭐ RETURN ⭐

she returns zero on success, and errno when any error occurs. simple. iconic. periodt 💅

ngl bestie, always check the return value — zero is the slay outcome, errno means something went sideways 😭
