💖 regs_get_kernel_stack_nth_addr(9) 💖

okay so welcome to the Kernel API Manual, bestie 🫶 — this is the page for regs_get_kernel_stack_nth_addr(9). The header is out here truncating it as regs_get_ker...ack_nth_addr(9) (iconic ellipsis behavior), but the NAME section has the full name.

✨ NAME ✨

regs_get_kernel_stack_nth_addr — get the address of the Nth entry on stack 💅

---

🌸 SYNOPSIS 🌸

unsigned long * regs_get_kernel_stack_nth_addr (struct pt_regs *regs ,
unsigned int n );

---

🎀 ARGUMENTS 🎀

• regs — pt_regs which contains kernel stack pointer. That's the little receipt that tells you where the kernel stack is at 💖
• n — stack entry number. Which entry are we checking, bestie? 🔢

---

🦋 DESCRIPTION 🦋

okay so regs_get_kernel_stack_nth returns the address of the n th entry of the kernel stack which is specified by regs. slay.

If the n th entry is NOT in the kernel stack, this returns NULL. no cap — that's the whole vibe check. ⚠️

tiny note, bestie: the description literally says regs_get_kernel_stack_nth (without _addr). That's exactly what the page says, so I'm not editing it — I'm just reporting the lore 🙈
