dwc2_hsotg_trytx(9)

💅 dwc2_hsotg_trytx ✨

okay so welcome to the Kernel API Manual bestie, today's main character is dwc2_hsotg_trytx and honestly? she's a tiny little check-and-send icon and we're obsessed 🎀

---

🌸 NAME 🌸

dwc2_hsotg_trytx — literally just checking to see if anything needs transmitting 🦋

---

✨ SYNOPSIS ✨

int dwc2_hsotg_trytx (struct dwc2_hsotg *hsotg , struct dwc2_hsotg_ep
*hs_ep );

---

🎀 ARGUMENTS 🎀

• hsotg — the driver state, aka the whole vibe of the driver, no cap 💜
• hs_ep — the driver endpoint you wanna check, your little specific bestie in question 🫶

---

🦋 DESCRIPTION 🦋

so the whole thing here is: she checks to see if there's a request that has data to send, and if there is, she makes an attempt to write that data into the FIFO. that's it. that's the function. peak efficiency, main character energy, periodt 🔥
