snd_usb_endpoint_start(9)

🎀 NAME 🎀

snd_usb_endpoint_start(9) — straight outta the Kernel API Manual — is literally here to start an snd_usb_endpoint. That’s the whole assignment, bestie 💅

---

✨ SYNOPSIS ✨

Okay so the signature is giving:

int snd_usb_endpoint_start (struct snd_usb_endpoint *ep );

---

🫶 ARGUMENTS 🫶

• ep — the endpoint to start. That’s it, that’s the arg 🎀

---

💖 DESCRIPTION 💖

A call to this function will increment the running count of the endpoint. In case it is not already running, the URBs for this endpoint will be submitted. Otherwise, this function does nothing.

⚠️ Balanced-calls check: must be balanced to calls of snd_usb_endpoint_stop 🫶

Returns an error if the URB submission failed, 0 in all other cases. No cap.
