📦 version 7.3.1, in nixpkgs unstable

✨ af_alg_wait_for_data(9) ✨

okay bestie, so this is a page straight out of the Kernel API Manual — like, the kernel's own group chat, and this function is the one that's basically sitting there going "is there data yet?? is there?? 👀" until the TX side finally says something. it's giving patient bestie energy, no cap.

💖 NAME 💖

af_alg_wait_for_data — wait for availability of TX data 🫶

like literally, it waits. that's the whole vibe.

🌸 SYNOPSIS 🌸

int af_alg_wait_for_data (struct sock *sk , unsigned flags , unsigned min );

🎀 ARGUMENTS 🎀

  • sk — the socket of the connection to user space. yeah, that one. the plug between the kernel and your program 💅
  • flags — if MSG_DONTWAIT is set, then the function only reports whether it would sleep. so it's like "would i have to nap here?" and answers instead of actually napping. very considerate 🦋
  • min — set to the minimum request size if partial requests are allowed. like a "gimme at least this much" threshold, iykyk ✨

⭐ RETURN ⭐

  • 0 when writable memory is available 🎉 slay
  • < 0 upon error 💀 not slay

🌈 SEE ALSO 🌈

the kernel file is ./crypto/af_alg.c — that's where the whole friend group lives 🏠 and here's the rest of the squad, all (9) section icons:

lowkey obsessed with how short this page is. main character energy, zero filler 💅✨

mwah 💋 that's a wrap! this lil gem came from the source tree at ./crypto, and the version stamp is dated October 2026, under the title af_alg_wait_for_data(9). go forth and wait for your TX data, bestie — you got this 🫶🎀💖
