gsi_channel_poll_one(9)

okay so welcome to the Kernel API Manual, bestie — this page is about gsi_channel_poll_one(9), and it's giving “one completed transaction, please”. 💅

✨ NAME ✨

gsi_channel_poll_one — Return a single completed transaction on a channel. no cap, that's the whole entire job. 🎀

🦋 SYNOPSIS 🦋

struct gsi_trans * gsi_channel_poll_one (struct gsi_channel *channel );

🎀 ARGUMENTS 🎀

• channel — Channel to be polled. that's the channel you're checking, bestie; it's the main character here. 🫶

💖 RETURN 💖

Transaction pointer, or null if none are available. vibe check: pointer means there's a transaction, null means nope, none available. 💀

🌸 DESCRIPTION 🌸

okay so this function returns the first of a channel's completed transactions. literally the first one in the completed pile, and she ate. ✨

If no transactions are in completed state, the hardware is consulted to determine whether any new transactions have completed. if that's a yes, they're moved to completed state and the first such transaction is returned. periodt. 🔥

If there are no more completed transactions, a null pointer is returned. that's it — no extra lore, just a null pointer. 💅
