✨ usb_endpoint_is_int_in(9) ✨

okay so bestie, welcome to the usb_endpoint_is_int_in page from the Kernel API Manual 💖 this one is short and sweet and honestly a little slay — it's a vibes-check function for USB endpoints, and you're gonna get it in like ten seconds, i promise 🫶

🌸 NAME 🌸

usb_endpoint_is_int_in — check if the endpoint is interrupt IN 👑

like, that's literally the whole job. she checks. she reports. she moves on. main character energy fr 💅

✨ SYNOPSIS ✨

int usb_endpoint_is_int_in (const struct usb_endpoint_descriptor *epd );

yes queen, that's the whole signature — she takes one pointer and hands you back an int 🎀

🦋 ARGUMENTS 🦋

  • epd — the endpoint to be checked 🌈 that's it. that's the argument. she's the endpoint you're side-eyeing and asking "are you an interrupt IN or not, bestie?"

💜 DESCRIPTION 💜

okay so here's the tea ☕ — this function returns true if the endpoint has interrupt transfer type and IN direction, and otherwise it returns false.

that's the entire plot. no plot twists. no cap 💀

so like, if the endpoint is giving interrupt + IN, she says yes ✨ if it's missing either one of those two things, she says no 🙈 periodt.

🔥 SEE ALSO 🔥

the whole friend group is here ngl — go read the rest of them, they're iconic 👑

lowkey a reminder that the interrupt-IN check is the combination of two separate facts, so if you're ever confused, peek at the direction and transfer-type helpers above and it'll all click 🧚

and that's the page!! 💖 brought to you by ./include/uapi/linux/usb, dated October 2026 — mwah, go check some endpoints, bestie, you're gonna ate 🎀💅🌟
