xdr_stream_d...opaque_fixed(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

xdr_stream_decode_opaque_fixed — decodes fixed-length opaque xdr data, bestie. That's the whole vibe. Like, it just pulls out a chunk of opaque data of a set size and slaps it where you tell it to. No cap. ✨

Oh and real quick — this is all from the Kernel API Manual, section 9, iykyk. 🎀

🌸 SYNOPSIS 🌸

ssize_t xdr_stream_decode_opaque_fixed (struct xdr_stream *xdr , void
*ptr , size_t len );

✨ ARGUMENTS ✨

  • xdr — pointer to xdr_stream. The stream you're decoding from, the main character of this whole operation. 🫶
  • ptr — location to store data. Like, the spot where the decoded goodies actually land. 👑
  • len — size of buffer pointed to by ptr. Gotta tell it how much room you've got, fr fr. 📏

💖 RETURN 💖

  • 0 on success. Slay. ✅
  • -EBADMSG on XDR buffer overflow. 😭 That's the "bestie it went wrong" number — your buffer just couldn't hold it.

🦋 SEE ALSO 🦋

Kernel file ./include/linux/sunrpc/xdr.h, plus the whole friend group:

The decode_opaque_fixed cousin to encode_opaque_fixed up there — they're literally siblings, and yes, both got invited to the function party. 🎉

And that's the page, bestie! 🍓 Big shoutout to ./include/linux/sunrpc for the source and October 2026 for the date — mwah 💋, couldn't have done it without ya! 🧚‍♀️💜
