cdns3_get_tdl(9)

💅 cdns3_get_tdl — Kernel API Manual, bestie edition 🎀

okay so we're in the cdns3 manual today and this one's a lil function called cdns3_get_tdl. she's small, she's specific, and she does one thing. let's get into it ✨

---

🌸 NAME 🌸

cdns3_get_tdl — gets the current tdl for the selected endpoint. that's it. that's her whole personality 🫶

---

✨ SYNOPSIS ✨

int cdns3_get_tdl (struct cdns3_device *priv_dev );

like, literally the entire signature. no notes. 💅

---

🎀 ARGUMENTS 🎀

• priv_dev — the extended gadget object 💖 (yes that's the actual description, she's an extended gadget object and we respect her for it)

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check you cannot skip: before you call this function, the appropriate endpoint must already be selected, and you do that with the cdns3_select_ep function. no cap. 🙈

like, think of it as — you gotta pick your endpoint first, then you can ask for the tdl. not the other way around. the order is the whole thing, iykyk. ⭐

fr fr do the cdns3_select_ep step first or don't come crying to me 😭
