💖 chp_get_chp_desc(9) — Kernel API Manual 💖

okay bestie, gather round the group chat: this is the chp_get_chp_desc(9) page from the Kernel API Manual. it's giving “tiny but essential kernel helper,” and we're gonna read it together, periodt. 💅

✨ NAME ✨

chp_get_chp_desc — return newly allocated channel-path description. that's it, that's the whole name, and honestly? iconic.

🛠️ SYNOPSIS 🛠️

struct channel_path_desc_fmt0 * chp_get_chp_desc (struct chp_id chpid );

no cap, that's the exact signature — copy it character for character or the compiler will absolutely side-eye you. 👀

🫶 ARGUMENTS 🫶

• chpid — channel-path ID. that's the one (1) argument, and she's carrying the whole channel-path identity vibe. 🦋

💖 DESCRIPTION 💖

okay so here's the tea: on success, this function returns a newly allocated copy of the channel-path description data associated with the given channel-path ID. newly allocated copy, bestie — not a re-used vibe, a fresh one.

On error? it returns NULL. that's the whole mood. error = NULL, no cap. 🫶
