offset_to_ptr(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… offset_to_ptr(9) β€” like, the Kernel API Manual, bestie ✨

Okay so quick vibe check: this is a page from the Kernel API Manual, and tbh it's short but iconic. It's giving "small function, big main character energy." Let's get into it 🫢


🌸 NAME 🌸

offset_to_ptr β€” converts a relative memory offset into an absolute pointer. fr fr, that's the whole glow-up πŸ¦‹


✨ SYNOPSIS ✨

void * offset_to_ptr (const int *off );

That's it. One function, one argument, no drama πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • off β€” the address of the 32-bit offset value πŸ’– like, not the offset itself, bestie, the address of it. Read that twice. iykyk.

πŸ¦‹ SEE ALSO πŸ¦‹

  • The kernel file ./include/linux/compiler.h β€” yes, that's a literal path, go look at it 🌈
  • data_race(9) β€” another manpage, go be nosy πŸ‘‘

ngl the whole page is like three lines long and I'm obsessed with it. no cap, sometimes the smallest functions are the most iconic 🧚

That's the whole thing, bestie β€” go forth and convert those offsets πŸ’œ

Signed off with love from the ./include/linux corner of the kernel, version date October 2026, under the watchful eye of the Kernel API Manual itself πŸŽ€βœ¨
