dpni_set_errors_behavior(9)

💅 dpni_set_errors_behavior(9) — like, the Kernel API Manual page, bestie

okay so this is dpni_set_errors_behavior from the Kernel API Manual (section 9, the kernel API girlies) and honestly? she's a little short but she works. Let's get into it 🫶

---

✨ NAME ✨

dpni_set_errors_behavior — literally just sets the errors behavior. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int dpni_set_errors_behavior (struct fsl_mc_io *mc_io , u32 cmd_flags ,
u16 token , struct dpni_error_cfg *cfg );

she returns an int, she takes four things, and yes you have to pass all of them. no shortcuts bestie 💀

---

🦋 ARGUMENTS 🦋

• mc_io — a pointer to the MC portal's I/O object. like, the portal. the I/O object. your entry point, your main character 🫶
• cmd_flags — command flags, and they're one or more of the MC_CMD_FLAG_ crew. pick your flags, queen 👑
• token — the token of the DPNI object. that's your little ID badge for the DPNI you're talking to 🎀
• cfg — the errors configuration. this is where you actually say what you want the errors behavior to be ✨

---

💜 DESCRIPTION 💜

so the one actual lore drop here is: this function may be called numerous times with different error masks. numerous. like, as many times as you want, with different masks each time. lowkey iconic that she's reusable like that 🔥

---

⭐ RETURN ⭐

ngl the page doesn't say anything here — the section exists and the content is just… not there. so we're not gonna invent return values, we're just gonna acknowledge the silence 🙈💀

🌈 real talk: keep the literal bits literal — the flags, the token, the config struct pointer — because the kernel does not accept vibes as arguments, bestie 😭
