💅 sclp_chp_read_info — a lil kernel API manual moment

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is sclp_chp_read_info. pull up a chair, we're learning about channel paths 🦋

✨ NAME ✨

sclp_chp_read_info — perform the read channel-path information sclp command

like, that's literally the whole vibe. it reads channel-path info. slay.

🌸 SYNOPSIS 🌸

int sclp_chp_read_info (struct sclp_chp_info *info );

one function, one argument, returns an int. no cap, that's it 💖

---

🎀 ARGUMENTS 🎀

• info — the resulting channel-path information data. think of it as the cute little basket where all the info ends up 🧺✨

👑 DESCRIPTION 👑

so here's the tea, bestie: this function performs the read channel-path information sclp command and then waits for completion. it's giving patient queen energy, fr fr — no running off before the job's done 💅

on success? it stores the channel-path information in info and returns 0. iconic. perfect. we love a zero return 🫶

return non-zero otherwise 😭 — that's your signal that things did not go the way we wanted.

lowkey important: 0 means success and the info landed in info. anything else means nope. don't @ me, that's just what the manpage says 🌈
