chp_new(9)

💅 chp_new — like, register a brand-new channel-path, bestie

okay so this is a page from the Kernel API Manual (that's the chp_new(9) manual, section 9, kernel-land only, iykyk) and honestly? it's short but it serves. 💖

---

✨ SYNOPSIS ✨

int chp_new (struct chp_id chpid );

like, that's the whole vibe. one function, one argument, returns an int. simple queen behavior. 👑

---

🎀 ARGUMENTS 🎀

• chpid — the channel-path ID. that's it, that's the whole thing. it's a struct chp_id and it tells the function which channel-path we're out here registering. 💅

---

🌸 DESCRIPTION 🌸

okay so here's the tea: chp_new() creates and registers a data structure that represents a new channel-path. so it's giving "make the thing, then put it on the official list" — both steps, one function, no cap. 🦋

it returns zero on success, and non-zero otherwise. so like… check your return value, bestie, because zero is the slay outcome and anything else is a vibe check failure. 😭

ngl this one's short but it's still main character energy — create the channel-path struct, register it, return 0 if it ate, non-zero if it didn't. periodt. 💀✨
