ccw_device_set_options(9)

okay so bestie, welcome to the Kernel API Manual page for ccw_device_set_options(9) — yes, we’re doing kernel option-setting and we’re gonna make it cute 💅✨

💖 NAME 💖

ccw_device_set_options — set some options

🎀 SYNOPSIS 🎀

int ccw_device_set_options (struct ccw_device *cdev , unsigned long
       flags );

✨ ARGUMENTS ✨

• cdev — the device for which the options are to be set. That’s the glow-up target 🫶
• flags — the options to be set. This is where the flag bits ride in.

🌸 DESCRIPTION 🌸

Bestie, the rule is simple: all flags specified in flags are set, and the remainder is left untouched. No touching the rest, no surprise edits — only the flags you named get set. It’s giving selective-update main character energy, fr fr.

🔥 RETURN 🔥

• 0 on success — we love a clean win ✨
• -EINVAL if an invalid flag combination would ensue — like, the combo doesn’t validate, so it hits you with that error 😭
