set_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, grab your matcha 🍓 because we're diving into set_link(9) from the Kernel API Manual and honestly? it's short, it's sweet, it's giving "small function, big responsibilities."

🌸 NAME 🌸

set_link — sets links according to params. that's it. that's the whole vibe. simple, iconic, no notes 💅

✨ SYNOPSIS ✨

here's the whole signature, copied exactly because we do not paraphrase code in this house:

int             set_link (struct qed_dev *cdev , struct qed_link_params
*params );

like look at that. int return, two pointers, done. main character energy fr fr 👑

🎀 ARGUMENTS 🎀

two arguments, both absolutely pulling their weight:

  • cdev — the Qed dev pointer. yes queen, this is your device handle, the whole reason we're here 🫶
  • params — the values used to override the default link configuration. so if you want something other than the default setup, this is where you say it. lowkey the fun one 🌈

⭐ RETURN ⭐

  • 0 on success 🎉
  • error otherwise 😭 (no, it does not tell you more than that here, and honestly same)

buckle up bestie, this list is long and we are not skipping a single one of them, because every single reference deserves its moment 💜
