dso__data_read_offset(9)

✨ dso__data_read_offset 💅

Okay bestie, welcome to the dso__data_read_offset page of the Kernel API Manual (that's the <italic>9</italic> section, iykyk) — this is literally the function that reads data from a dso file offset, and we're gonna get you across the finish line 🫶

✨ NAME ✨

dso__data_read_offset — read data from dso file offset 🌸

---

✨ SYNOPSIS ✨

ssize_t dso__data_read_offset (struct dso *dso , struct machine *machine
, u64 offset , u8 *data , ssize_t size );

That's the whole vibe check — five args, one ssize_t return, no cap 💅

---

✨ ARGUMENTS ✨

• dso — the dso object 👑
• machine — the machine object 🦋
• offset — file offset ⭐
• data — buffer to store data 🎀
• size — size of the data buffer 💖

---

✨ DESCRIPTION ✨

So like, this is the external interface to read data from a dso file offset, periodt. It opens the dso data file and then uses cached_read to actually get the data out 🔥

That's it, that's the whole lore — no hidden plot twists, no extra behaviour to warn you about 🙈
