dwarf_read_addr(9)

🌸 NAME 🌸

okay so this is dwarf_read_addr(9) from the Kernel API Manual, and it is literally here to read dwarf data 💖

dwarf_read_addr — read dwarf data ✨

---

✨ SYNOPSIS ✨

int dwarf_read_addr (unsigned long *src , unsigned long *dst );

---

💖 ARGUMENTS 💖

• src — the source address of the data 🎀 like, that's where the data is coming from, bestie.
• dst — the destination address to store the data to 🫶 that's where it's going.

---

🦋 DESCRIPTION 🦋

okay so the vibe is: read n bytes from src, where n is literally the size of an address on the native machine 👑 no cap.

we return the number of bytes read, and it should always be n. like, always always. that's the whole point bestie 💅

also we have to be careful when reading from src and writing to dst, because they can be arbitrarily aligned 😭 this is the part where you don't just assume everything is cute and lined up perfectly.

and yes — return n, the number of bytes read. periodt. 🦋
