time_before_eq(9)

✨ time_before_eq(9) ✨

okay so bestie, welcome to the kernel API manual, section 9, and today's main character is time_before_eq 💅 she's from ./tools/sched_ext/include/scx and she's literally just here to answer one question: is time a before, or the same as, time b? that's it. that's the whole vibe check. 🎀

---

🌸 NAME 🌸

time_before_eq — returns true if the time a is before or the same as time b. no cap, that's the entire job. 🦋

---

✨ SYNOPSIS ✨

bool time_before_eq (u64 a , u64 b );

like yes, that's the whole signature, she's lowkey minimal and we respect it. 💜

---

🫶 ARGUMENTS 🫶

• a — the first comparable, typed as u64. she goes first. main character energy, honestly. 👑
• b — the second comparable, also a u64. she's the one a gets compared against. 🍓

---

🔥 RETURN 🔥

true is time a is before or the same as time b, otherwise false. (yes, the manpage literally says "true is time a..." and honestly? iconic typo, we're keeping it fr fr. 😭) so like — if a comes before b, or they're exactly equal, you get true. anything else and it's false, periodt. 💅

ngl, the "or the same as" part is doing a LOT of heavy lifting here — equal counts as before-ish. don't forget that. 🌟
