mas_store(9)

💅 mas_store(9) — the Kernel API Manual, bestie edition 🍓

okay so real talk, this is mas_store(9) from the Kernel API Manual, and honestly? iconic behaviour from the maple tree crew. let's get into it 🧚

---

✨ NAME ✨

mas_store — stores an @entry. that's it, that's the whole job, and she does it slayfully 💖

---

🌸 SYNOPSIS 🌸

void * mas_store (struct ma_state *mas , void *entry );

look at her. simple signature, zero drama, all vibes ✨

---

🎀 ARGUMENTS 🎀

• mas — the maple state 🍁 like, the whole situation you're working inside of.
• entry — the entry you're storing. the thing. the icon. the moment 💅

---

🦋 DESCRIPTION 🦋

so here's the tea, bestie: mas->index and mas->last are what you use to set the range for the entry 🫶 that's the whole mechanic. the range comes from the state, not from extra args, periodt.

---

⭐ RETURN ⭐

returns the first entry between mas->index and mas->last, or NULL 💀 no cap, that's it.

ngl, if you get NULL back, don't come for me — that's just what the manpage says 🙈
