✨ tb_lc_is_usb_plugged 💅

okay so this is a kernel API manual page, bestie — the function is literally called tb_lc_is_usb_plugged and it lives in section 9 of the manual (that's the kernel API section, iykyk). It's giving "quick little yes-or-no question" energy, and honestly? we love a function that just tells you the truth. 🫶

🌸 NAME 🌸

tb_lc_is_usb_plugged — is there a USB device connected to this port or not? That's it. That's the whole gig. 💖

🎀 SYNOPSIS 🎀

bool tb_lc_is_usb_plugged (struct tb_port *port );

it returns a bool, it takes one argument, it does not have time for drama. slay. ✨

🦋 ARGUMENTS 🦋

  • port — the device router lane 0 adapter. that's the thing you're asking about. like pointing at a door and being like "is somebody in there?" 🚪👀

⭐ RETURN ⭐

  • true — yesss, the port has a USB Type-C device connected to it. plugged in. connected. living its best life. 🔌💖
  • false — nope, nothing hooked up to that port. empty. quiet. no device, no vibes. 😭
