📦 version 7.3.1, in nixpkgs unstable

💅 fm10k_mbx_pushed_tail_len(9) — like, the Kernel API Manual page, bestie 🎀

okay so real talk, we're deep in the Kernel API Manual today and this little function is honestly kind of iconic. It's a tiny one. A snack, if you will. But it's a useful snack and we're gonna stan it properly. ✨

🌸 NAME 🌸

fm10k_mbx_pushed_tail_len — Retrieve the length of message being pushed 🫶

like... it tells you how long the thing you're shoving in there is. that's the whole vibe. 💅

🦋 SYNOPSIS 🦋

u16 fm10k_mbx_pushed_tail_len (struct fm10k_mbx_info *mbx );

not me being obsessed with how short that is. main character energy fr fr 🔥

💖 ARGUMENTS 💖

  • mbx — pointer to mailbox 💌 (yes bestie, that's the whole argument list, we love a low-effort queen)

✨ DESCRIPTION ✨

okay so picture this: there is a message, right? and it is currently being pushed onto the tail of the Rx queue 👀. This function? It returns the length of that message. That's it. That's the lore. 🌈

so if you were like "hmm how long is the thing I'm pushing rn" — this is your girl. she will tell you. respectfully. with a u16 return type because we're not doing anything unhinged here. 🧚

no cap, it's giving "small but essential helper function" and I respect it immensely. 👑
