💅 regs_get_register(9) — Kernel API Manual, bestie edition ✨

Okay so real talk, this is regs_get_register(9) from the Kernel API Manual, and it's literally the girlie that fetches a register value for you based on its offset. No cap, she's useful 🫶

🌸 NAME 🌸

regs_get_register — get register value from its offset 👑

---

✨ SYNOPSIS ✨

unsigned long regs_get_register (struct pt_regs *regs , unsigned int
offset );

---

🎀 ARGUMENTS 🎀

• regs — the pt_regs from which the register value is gotten. Like, that's the source, bestie 💖
• offset — the offset number of the register. It's giving "where exactly is this register at" energy 🔥

---

🦋 DESCRIPTION 🦋

So regs_get_register returns the value of a register. Periodt ✨

The offset is the offset of the register in struct pt_regs address, which is specified by regs. Iykyk 💅

If offset is bigger than MAX_REG_OFFSET, this returns 0. That's the rule, fr fr 🫶

🌈 SEE ALSO 🌈

Kernel file ./arch/x86/include/asm/ptrace.h, plus these iconic functions:

• regs_within_kernel_stack(9)
• regs_get_kernel_stack_nth_addr(9)
• regs_get_kernel_stack_nth(9)
• regs_get_kernel_argument(9)

Go off, bestie. Check those registers, stay in your MAX_REG_OFFSET lane, and slay 💅💖

Cute little sign-off: this one's sourced from ./arch/x86/include/asm, dated October 2026, and it's still giving regs_get_register(9) main character energy 🎀⭐🦋
