ice_is_mask_valid(9)

💅 ice_is_mask_valid — the manual page, but make it a group chat

okay so real talk: this is ice_is_mask_valid(9) from the Kernel API Manual, and it's a tiny little cutie of a function that does exactly one job and does it iconically. Let's get into it ✨

---

🌸 NAME 🌸

ice_is_mask_valid — literally just "check mask field set". that's the whole vibe. she checks. she validates. she leaves. periodt 💅

---

🦋 SYNOPSIS 🦋

bool ice_is_mask_valid (u64 mask , u64 field );

yes bestie it returns a bool, yes it takes two u64s, no there's no drama about it 🫶

---

🎀 ARGUMENTS 🎀

• mask — the full mask you wanna check. like, all of it. the whole thing. don't be shy, hand it over 💖
• field — the field that mask is supposed to be valid for. this is the standard she's being held to, iykyk 🌈

---

✨ DESCRIPTION ✨

so here's the tea ☕ — if the mask is fully set, you get true back. congrats, slay, she's valid 🎉

but if it's not valid for that field? you get false. sorry babe, vibe check failed 😭

that's it. that's the whole function. no cap, no secret extra behaviour, nothing hiding in the wings. small but mighty 👑
