scx_cmask_for_each_cid(9)

okay so bestie, this is the scx_cmask_for_each_cid(9) page from the Kernel API Manual — and it's literally the “walk the set cids” moment. 💅✨

🌸 NAME 🌸

scx_cmask_for_each_cid — iterate set cids in @m. That's the whole assignment, no cap. 🫶

✨ SYNOPSIS ✨

the call looks like this, copy-paste energy:

scx_cmask_for_each_cid (cid , m );

🎀 ARGUMENTS 🎀

• cid — a s32 loop var that receives each set cid in turn. It's the lil main character that changes every round. 🌟
• m — the cmask to iterate. This is the vibe check source. 🦋

🦋 DESCRIPTION 🦋

Okay so what it does: it visits the set bits inside m's active range, and it does that in ascending order. No chaos, no random order — ascending, periodt. 🔥

It scans only the words that the active range spans. Head and tail padding is kept zero, so no per-cid range check is needed. That's the flex: the padding does the bouncer duty for you. 💅
