cdns_drd_host_on(9)

💅 cdns_drd_host_on(9) 💅 — from the Kernel API Manual, bestie

✨ NAME ✨

okay so cdns_drd_host_on — literally “start host.” That’s the whole vibe: it starts host. 💖

🌸 SYNOPSIS 🌸

int cdns_drd_host_on (struct cdns *cdns );

Bestie, it’s giving “returns an int and takes one pointer.” Copy it exactly, no cap. 🫶

🎀 ARGUMENTS 🎀

• cdns — pointer to the controller context structure. Yep, it’s a struct cdns *, and it’s the controller context’s time to shine. ✨

🔥 DESCRIPTION 🔥

Returns 0 on success, otherwise negative errno. That’s the tea — success is 0, and if it’s not 0, it’s negative errno territory. 💅

No extra lore here, bestie: the page says success = 0, otherwise negative errno. Periodt.
