💖 NAME 💖

usb_check_bulk_endpoints — Check whether an interface's current altsetting contains a set of bulk endpoints with the given addresses.

This is the Kernel API Manual page for usb_check_bulk_endpoints(9), bestie. It's giving endpoint vibe check, and the facts below are all canon. 💅

✨ SYNOPSIS ✨

bool usb_check_bulk_endpoints (const struct usb_interface *intf , const
       u8 *ep_addrs );

🫶 ARGUMENTS 🫶

• intf — the interface whose current altsetting should be searched. Yes, that exact one.
• ep_addrs — a 0-terminated array of the endpoint addresses (number and direction) to look for. iykyk

🌸 DESCRIPTION 🌸

So the function searches for endpoints with the specified addresses and checks their types. That's the whole assignment — no side quests. ✨

💅 RETURN 💅

It returns true if all the endpoints are found and are bulk, and false otherwise. Fr fr, that's the whole verdict. 👑
