get_ep_limit(9)

✨ get_ep_limit(9) ✨

okay so bestie, this page is straight out of the Kernel API Manual — tiny page, but it still ate. 💅

🌸 NAME 🌸

get_ep_limit — get the maximum data legnth for this endpoint

(yes, legnth is literally the spelling in the original — no cap, we're keeping it 🫶)

🎀 SYNOPSIS 🎀

unsigned int get_ep_limit (struct dwc2_hsotg_ep *hs_ep );

💖 ARGUMENTS 💖

• hs_ep — the endpoint. That's your struct dwc2_hsotg_ep * bestie right there. 🦋

🔥 DESCRIPTION 🔥

So this function returns the maximum data that can be queued in one go on a given endpoint. The whole reason? So that transfers that are too long can be split. That's the vibe: find the one-go queue ceiling, then split the too-long transfer. Periodt. 💫
