xdr_stream_subsegment(9)

📦 version 7.3.1, in nixpkgs unstable

💅 xdr_stream_subsegment(9) 💅

okay bestie, welcome to the Kernel API Manual — this is the page for xdr_stream_subsegment(9), and it is lowkey iconic for doing exactly one little slice-of-XDR job. 🎀

✨ NAME ✨

xdr_stream_subsegment — set @subbuf to a portion of @xdr. That's the whole name, and it ate. 💅

🦋 SYNOPSIS 🦋

bool xdr_stream_subsegment (struct xdr_stream *xdr , struct xdr_buf
*subbuf , unsigned int nbytes );

🎀 ARGUMENTS 🎀

  • xdr — an xdr_stream set up for decoding. Like your notes app, but for XDR data, and it's ready to scroll. ✨
  • subbuf — the result buffer. This is where the little portion lands. 🫶
  • nbytes — length of xdr to extract, in bytes. Actual bytes, not vibes. 💖

🌸 DESCRIPTION 🌸

Sets up subbuf to represent a portion of xdr. The portion starts at the current offset in xdr, and extends for a length of nbytes. If this is successful, xdr is advanced to the next XDR data item following that portion.

Return values: true: subbuf has been initialized, and xdr has been advanced. false: a bounds error has occurred.

bestie, the false case is a bounds error — that's the vibe check failing, so don't ignore it. 😭

🌈 SEE ALSO 🌈

The kernel file ./net/sunrpc/xdr.c is on the list, and honestly the whole XDR friend group pulled up too:
