💅 panthor_subm...ignal_fences(9) — like, the Kernel API Manual, bestie 🎀

Okay so real talk, this page lives in the Kernel API Manual and it's all about panthor_submit_ctx_update_job_sync_signal_fences — yes that name is a whole paragraph, we don't talk about it 😭 — and it does exactly one iconic little job: it updates the fences on the signal operations that a job specified. That's the vibe. That's the whole gig. ✨

🌸 NAME 🌸

panthor_submit_ctx_update_job_sync_signal_fences — updates the fences on the signal operations specified by a job. Lowkey self-explanatory once you stop hyperventilating at the length of the name, ngl. 💜

---

🦋 SYNOPSIS 🦋

int panthor_submit_ctx_update_job_sync_signal_fences (struct
       panthor_submit_ctx *ctx , u32 job_idx );

Like, it hands back an int. That's it. That's the whole signature. She's not complicated, she's just got a long name. 💅

---

✨ ARGUMENTS ✨

• ctx — the context you're searching for the signal operation in. Think of it as the group chat you're scrolling through looking for That One Message. 🫶
• job_idx — the index of the job you wanna operate on. It's a u32, it's a number, it points at which job is the main character today. 👑

---

🔥 RETURN 🔥

0 on success, and a negative error code otherwise. So like, zero means slay, negative means something went sideways and you should probably read the error code instead of just yelling. 💀
