pxa_ep_fifo_flush(9)

🌸 NAME 🌸

pxa_ep_fifo_flush — flushes one endpoint. okay so this is the pxa_ep_fifo_flush(9) page from the Kernel API Manual, and it's giving “clean out one endpoint’s data” energy 💅✨

✨ SYNOPSIS ✨

void pxa_ep_fifo_flush (struct usb_ep *_ep );

That’s the whole signature, bestie: void, one argument, no extra drama 🎀

🎀 ARGUMENTS 🎀

• _ep — a usb endpoint. that’s the endpoint this function takes 🫶

🦋 DESCRIPTION 🦋

This function discards all data in one endpoint (IN or OUT), except the control endpoint. periodt 💜 so if you were wondering whether the control endpoint gets included: nope, it is not invited to that party 🌈
