tipc_poll(9)

🌸 tipc_poll — read and possibly block on pollmask 🌸

okay so real talk, this is tipc_poll(9) from the Kernel API Manual, and it's genuinely iconic — let's get into it 💅

✨ SYNOPSIS ✨

__poll_t tipc_poll (struct file *file , struct socket *sock , poll_table *wait );

🫶 ARGUMENTS 🫶

• file — the file structure that's besties with the socket, like they're literally linked
• sock — the socket we're calculating the poll bits for, main character energy fr
• wait — ??? … yeah bestie the docs literally just say that 😭 no cap, that's all we get

⭐ RETURN ⭐

the pollmask value, that's it, that's the tea 🎀

💖 DESCRIPTION 💖

COMMENTARY: so the vibe here is that the usual socket locking mechanisms are lowkey NOT useful in this spot, because the pollmask info is potentially out-of-date like the moment this routine exits 💀 TCP and the other protocols seem to rely on higher-level poll routines to handle any preventable race conditions, so TIPC is gonna do the same thing … periodt, we're matching their energy ✨

IMPORTANT: the fact that a read or write operation is indicated does NOT imply that the operation will succeed — it merely means it should be performed and will not block 🙈 like pls don't read too much into it, it's giving "hint, not a promise"
