mas_find_setup(9)

💅 mas_find_setup(9) — like, the internal setup girly for mas_find*() 💅

okay so bestie, grab a lil snack 🍓 because we're diving into mas_find_setup, straight out of the Kernel API Manual — this is kernel-level maple tree lore and honestly it's giving "backstage pass, not the main show" energy ✨

---

🌸 NAME 🌸

mas_find_setup — an internal function whose whole job is setting up the mas_find*() crew 🫶 like, it's the hype girl backstage getting everybody ready, not the one on stage. iykyk 💅

---

✨ SYNOPSIS ✨

bool mas_find_setup (struct ma_state *mas , unsigned long max , void
       **entry );

look at her. she returns a bool, she takes three args, she's little but she's important, no cap 🎀

---

🦋 ARGUMENTS 🦋

okay so here's the cast of characters, and yes every single one matters:

• mas — the maple state 💖 literally the whole vibe container, this is the struct ma_state we're working inside of
• max — the maximum index 👑 it's an unsigned long, and it's, well, the max. the ceiling. the limit. the "don't go past this bestie" line
• entry — pointer to the entry 🌈 classic void ** situation: a pointer, to a pointer, to the entry. very iconic, very pointer-to-pointer of her

---

🔥 RETURN 🔥

• returns true → the entry is the answer, we found it, slay, mission accomplished 💅✨
• returns false → nah, entry is not the answer, keep it moving bestie 😭

that's it. that's the whole return contract. true or false, periodt.

lowkey a reminder bestie: this one is flagged internal in its NAME line, so treat it like the backstage crew it is — it's not the public-facing finder, it's the setup step for the finders. don't be weird about it 💀

okay that's the page!! source/version vibes: this one's from ./lib 🫶 and it's dated October 2026 — a whole future date, main character energy fr fr. stay hydrated, read your maple tree code, and remember: true if entry is the answer, false otherwise. mwah 💖🎀🦋⭐👑
