💅 NAME 💅

okay so bestie, tb_dp_port_is_enabled — this is the one that tells you whether a DP adapter port is enabled. That's it, that's the whole vibe check. ✨

This page lives in the Kernel API Manual, and the function itself is shown as tb_dp_port_is_enabled(9) — the (9) is giving kernel-API section energy, iykyk. 🎀

✨ SYNOPSIS ✨

bool tb_dp_port_is_enabled (struct tb_port *port );

literally just hand it a struct tb_port * and it hands you back a bool. no cap. 🦋

🌸 ARGUMENTS 🌸

• port — the DP adapter port you want to check. that's the whole assignment, bestie. 🔍

---

💖 RETURN 💖

true if the DP port is enabled. false otherwise. periodt. 💅

no in-between, no "maybe", no mysterious third state. it's giving binary. 🫶

this is the part where the manpage just dumps the whole friend group, and honestly? iconic. 👑
