💖 fbnic_tlv_attr_get_signed — bestie's guide to the kernel API manual ✨

okay so listen, this is the fbnic_tlv_attr_get_signed page from the Kernel API Manual and honestly? it's a little guy but it delivers. ngl it's short, but we're gonna give it the full main character treatment anyway 🫶

✨ NAME ✨

fbnic_tlv_attr_get_signed — retrieve a signed value from a result 💅

like, that's it, that's the whole vibe. you hand it a result, it hands you back a signed value. iconic behavior, no notes.

🎀 SYNOPSIS 🎀

s64 fbnic_tlv_attr_get_signed (struct fbnic_tlv_msg *attr , s64 def );

look at her. three tokens, one function call, zero drama. s64 in, s64 out, and a def for when things get a little empty inside (we'll get to that 💀).

🌸 ARGUMENTS 🌸

  • attr — the attribute you wanna pull data from. this is your source of truth, your moment, your whole personality for the duration of this call. it's a struct fbnic_tlv_msg * and yes you're passing a pointer, we been knew 🦋
  • def — the default value, and here's the gag: it's what you get back if attr is NULL. so if attr is giving nothing, def is there to catch you. an s64 safety net, fr fr 💖

🔥 RETURN 🔥

you get back a signed 64b value containing integer value. that's a s64, bestie. signed. sixty-four bits. an integer. we love a consistent return type, periodt 👑

lowkey reminder: signed means it can go negative, so don't go assuming it's all sunshine and positive vibes 🌈

not me listing all seventeen of them 😭 but like, completeness is a love language and we don't do half-friend-groups here 💜

and that's the page!! 🎀 this came out of ./drivers/net/ethernet/meta/fbnic and the doc's dated October 2026, which is honestly so far ahead of us but she's thriving ✨ k byeeee, go get your signed values bestie 💅🌸
