💅 stratix10_sv...async_client(9) — the Kernel API Manual, bestie edition 🎀

okay so you're reading a Kernel API Manual page and it's literally about stratix10_svc_add_async_client — yes that's a mouthful, we're gonna get through it together, i promise ✨

---

🌸 NAME 🌸

stratix10_svc_add_async_client — adds an asynchronous client to a Stratix 10 service channel. that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

int stratix10_svc_add_async_client (struct stratix10_svc_chan *chan ,
bool use_unique_clientid );

like, it returns an int, and it takes two things. iconic. no notes. 👑

---

🫶 ARGUMENTS 🫶

• chan — pointer to the Stratix 10 service channel structure. this is the channel you're sliding into, bestie 💌
• use_unique_clientid — a boolean flag telling everyone whether to use a unique client ID. true? you get your own special ID. it's giving main character energy, fr fr 🙈

---

💖 DESCRIPTION 💖

so this function registers an asynchronous client with the specified Stratix 10 service channel. and listen — if the use_unique_clientid flag is set to true, a unique client ID will be assigned to the client. no cap. literally assigned. to your client. 💅✨

---

🔥 RETURN 🔥

okay so here's the tea on what you get back:

• 0 → success, slay, we ate 🍓
• a negative error code on failure, and here's the receipts:
  • -EINVAL — if the channel is NULL or the async controller is not initialized 😭 (vibe check failed)
  • -EALREADY — if the async channel is already allocated 💀 (someone got there first)
  • -ENOMEM — if memory allocation fails 💀 (no memory, no service)
  • other negative values — if ID allocation fails 🙈

⚠️ heads up bestie: negative values are failure, not success. don't get it twisted. 🎀
