rio_alloc_net(9)

rio_alloc_net(9) 💖

okay so bestie, welcome to the Kernel API Manual page for rio_alloc_net(9) — it's giving "small function, big RIO network setup energy" and I'm kind of obsessed. 🦋 This is the one that gets a new RIO network data structure all cute and ready, and the details are literally right here. ✨

✨ NAME ✨

rio_alloc_net — allocate and initialize a new RIO network data structure. 🎀

🦋 SYNOPSIS 🦋

struct rio_net * rio_alloc_net (struct rio_mport *mport );

💅 ARGUMENTS 💅

• mport — the Master port associated with the RIO network. That's the whole argument list, bestie — one icon, one job. 💅

🔥 DESCRIPTION 🔥

okay so here's the tea: rio_alloc_net allocates a RIO network structure, initializes per-network list heads, and adds the associated master port to the network list of associated master ports. It's giving "set up the network bookkeeping so everything can slay later" energy. 🧚

It returns a RIO network pointer on success, or NULL on failure. No cap — that's the success/failure situation, and NULL is the "nope, didn't work" vibe. 😭
