💜 xdr_stream_decode_u64 — the kernel API manual, bestie edition ✨

okay so this is the page for xdr_stream_decode_u64(9) and like… it does exactly one thing and it does it slayfully: Decode a 64-bit integer 🎀 that's the name, that's the whole vibe, no notes.

✨ NAME ✨

xdr_stream_decode_u64 — decode a 64-bit integer 💅

🌸 SYNOPSIS 🌸

ssize_t xdr_stream_decode_u64 (struct xdr_stream *xdr , __u64 *ptr );

that's it. that's the whole signature. she's compact, she's iconic, she takes exactly two arguments and she does not do small talk 🫶

🦋 ARGUMENTS 🦋

  • xdr — pointer to xdr_stream ⭐ this is your stream, your main character, the thing you're reading out of.
  • ptr — location to store the 64-bit integer 💖 you hand her somewhere to put the goods, and she puts the goods there.

🔥 RETURN 🔥

  • 0 on success 👑 everything went fine, no drama, we love a clean zero.
  • -EBADMSG on XDR buffer overflow 💀 the buffer said "not today" and there was more to read than there was buffer to read it from. ngl that one hurts but at least it's honest.

💀 SEE ALSO 💀

so the kernel file is ./include/linux/sunrpc/xdr.h — that's the home base, the mothership, the place where all of these live 🧚 and like, the whole friend group is here, so let's shout them out:

like… it's giving full ensemble cast 🌈 every single one of them, no cap, not a single name skipped 💜

lowkey reminder: if she returns -EBADMSG, that's your buffer overflow situation, not a you problem to ignore 🙈 check it fr fr.

and that's the page!! 🍓 this little gem lives in the kernel source under ./include/linux/sunrpc, it's from October 2026, and it's part of the Kernel API Manual ⭐ ily, go read your xdr headers, mwah 💅🎀💖
