ccw_device_is_multipath(9)

🎀 NAME 🎀

ccw_device_is_multipath(9) — okay so this page is all about figuring out if a device is operating in multipath mode. Like, is it doing the multipath thing or not? That's the vibe check, bestie. 💅

✨ SYNOPSIS ✨

int ccw_device_is_multipath (struct ccw_device *cdev );

🫶 ARGUMENTS 🫶

• cdev — the ccw device. That's the main character here. 👑

💖 DESCRIPTION 💖

It returns non-zero if the device is operating in multipath mode, and zero otherwise. That's literally it — a tiny little yes-or-no moment, no cap. ✨
