pt_regs_to_gdb_regs(9)

💅 pt_regs_to_gdb_regs(9) — like, the Kernel API Manual page you actually wanna read ✨

okay bestie, welcome to the glow-up of pt_regs_to_gdb_regs(9) from the Kernel API Manual. she's a tiny function but she's doing main character work, fr fr. 🎀

---

🌸 NAME 🌸

pt_regs_to_gdb_regs — literally just "Convert ptrace regs to GDB regs", that's the whole vibe, no cap 💖

---

✨ SYNOPSIS ✨

void pt_regs_to_gdb_regs (unsigned long *gdb_regs , struct pt_regs *regs
);

that's it. that's the whole signature. slay. 🫶

---

🦋 ARGUMENTS 🦋

• gdb_regs — hiii this is a pointer, okay, and it's the spot that holds the registers in the order GDB wants. not the order you want, not the order your fave wants — GDB's order. respect it. 👑
• regs — the struct pt_regs of the current process. like, the actual current process. her. 💅

---

💜 DESCRIPTION 💜

okay so here's the tea: this function takes the pt_regs sitting in regs and converts them into the format for registers that GDB expects, and then it stores that into gdb_regs. 🧚

that's it. that's the conversion. structural, iconic, to the point. no notes. ⭐
