💅 chp_process_crw(9) — like, the Kernel API Manual page, bestie

okay so this is chp_process_crw(9), straight out of the Kernel API Manual — s390 channel-path lore, and honestly? it's giving niche icon energy. let's get into it 🎀

✨ NAME ✨

chp_process_crw — process channel-path status change 🦋

like, the function that handles the "hey, something about a channel path just changed" of it all.

---

✨ SYNOPSIS ✨

void chp_process_crw (struct crw *crw0 , struct crw *crw1 , int overflow
);

that's it. that's the whole vibe. void return, three args, no notes 💅

---

✨ ARGUMENTS ✨

• crw0 — the channel report-word that gets handed off to the handler 🌸
• crw1 — the second channel-report word… and bestie, it's always NULL. always. don't come for it, it's just there for the bit 🙈
• overflow — the crw overflow indication, aka the "oops there were too many of these" flag 💀

---

✨ DESCRIPTION ✨

so basically it handles channel-report-words that are telling you the status of a channel-path has changed. that's the whole job. it processes the crw, notices the change, does the honors. lowkey iconic, highkey necessary ✨
