💖 cdns3_init_ep0(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — yes we're literally reading kernel docs together, this is our bonding era 🫶. Today's main character is cdns3_init_ep0, and it's giving "small function, big responsibility" no cap 👑

✨ NAME ✨

cdns3_init_ep0 — initializes software endpoint 0 of gadget 🎀

like, it sets up ep0 so your gadget can actually, y'know, exist 💅

🌸 SYNOPSIS 🌸

int cdns3_init_ep0 (struct cdns3_device *priv_dev , struct
       cdns3_endpoint *priv_ep );

ok so it takes two structs and hands you back an int. that's the whole vibe fr fr 🦋

🎀 ARGUMENTS 🎀

  • priv_dev — the extended gadget object 🧚 — like the whole gadget's big-picture self
  • priv_ep — the extended endpoint object ⭐ — the specific endpoint we're out here initializing

💜 DESCRIPTION 💜

Returns 0 on success else error code ✨

that's it. that's the description. short and iconic, we respect it 🙈💅

lowkey love a function that tells you exactly what it does and dips. no notes. 👑
