💅 media_pad_remote_pad_unique(9) — Kernel API Manual realness 💅

okay bestie, welcome to the Kernel API Manual page for media_pad_remote_pad_unique. Let's get into the pad-finding lore. 🎀

✨ NAME ✨

media_pad_remote_pad_unique — find a remote pad connected to a pad. That's it. That's the mission. 💖

🦋 SYNOPSIS 🦋

struct media_pad * media_pad_remote_pad_unique (const struct media_pad
       *pad );

🎀 ARGUMENTS 🎀

• pad — the pad. literally just the pad you're investigating, bestie. 🫶

💖 DESCRIPTION 💖

okay so this helper searches for and returns a remote pad that's connected to pad through an enabled link. If multiple (or no) remote pads are found, an error gets returned, periodt. 😭

The uniqueness constraint is the whole moment: it makes this helper function suitable for entities that support a single active source at a time on a given pad. iykyk. ✨

🔥 RETURN 🔥

A pointer to the remote pad, or one of the following error pointers if an error occurs:

• -ENOTUNIQ — multiple links are enabled. 💀
• -ENOLINK — no connected pad found. 🙈
