p9_check_errors(9)

✨ p9_check_errors 💅

okay so this is a page from the Kernel API Manual, and bestie, we're about to get into it 🫶 the function is literally called p9_check_errors and it does exactly what it says on the tin — no cap.

🌸 NAME 🌸

p9_check_errors — check 9p packet for error return and process it

like... it peeks at your 9p packet, sees if there's an error in there, and handles it. iconic behavior honestly 💖

---

🎀 SYNOPSIS 🎀

int p9_check_errors (struct p9_client *c , struct p9_req_t *req );

---

🦋 ARGUMENTS 🦋

• c — current client instance ✨ like, the client you're working with right now
• req — request to parse and check for error conditions 🔍 this is the one getting the vibe check

---

💜 DESCRIPTION 💜

returns error code if one is discovered, otherwise returns 0 💀

that's it. that's the whole thing. if it finds an error it hands you the error code, and if everything's chill it gives you a big fat 0. slay 🌈

this will have to be more complicated if we have multiple error packet types

not me pointing out that this whole thing is lowkey living its best simple life 😭 the source literally says it'll have to be more complicated if there are multiple error packet types — so like, future problem, not today's problem. periodt. 👑
