dfl_feature_ioctl_set_irq(9)

✨ NAME ✨ (dfl_feature_ioctl_set_irq)

okay so bestie, this page is straight from the Kernel API Manual and it's all about dfl_feature_ioctl_set_irq — the dfl feature _SET_IRQ ioctl interface. no cap, that's the whole vibe.

🌸 SYNOPSIS 🌸

long dfl_feature_ioctl_set_irq (struct platform_device *pdev , struct
       dfl_feature *feature , unsigned long arg );

🎀 ARGUMENTS 🎀

• pdev — the feature device which has the sub feature, like the main character energy of this operation 💅
• feature — the dfl sub feature, lowkey the sidekick but still iconic
• arg — the ioctl argument, just passing it through, no cap

🔥 RETURN 🔥

returns 0 on success, and a negative error code otherwise. so if you see a negative number, something's not slaying 😭 periodt.
