mas_set(9)

💖 NAME 💖

mas_set — and yes bestie, this is the mas_set(9) page from the Kernel API Manual. It sets up the Maple Tree operation state for a different index ✨

---

🦋 SYNOPSIS 🦋

void mas_set (struct ma_state *mas , unsigned long index );

It returns void, so there’s no return value to catch — periodt 💅

---

🎀 ARGUMENTS 🎀

• mas — the Maple Tree operation state, your main character struct 🫶
• index — the new index into the Maple Tree, fresh and ready 🌸

---

✨ DESCRIPTION ✨

Okay so here’s the vibe: mas_set moves the operation state so it refers to a different index. The way that works is it has the effect of starting a walk from the top — iconic, honestly 👑

If you wanna move to an adjacent index instead, go see mas_next, iykyk 🦋
