STRUCT PIPE_BUFFER(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct pipe_buffer(9) 💖

okay so this is a page straight out of the Kernel API Manual, and it's literally all about struct pipe_buffer — a linux kernel pipe buffer. that's it, that's the whole vibe. it's the lil' container that holds the data flowing through a pipe, and honestly? iconic. 🎀

✨ NAME ✨

struct pipe_buffer — a linux kernel pipe buffer. no cap, that's the actual description. 🫶

🌸 SYNOPSIS 🌸

struct pipe_buffer {
    struct page *page;
    unsigned int offset, len;
    const struct pipe_buf_operations *ops;
    unsigned int flags;
    unsigned long private;
 };

like, look at her. five fields. perfectly balanced. main character energy fr fr. 💅

🦋 Members 🦋

okay bestie, let's go through the squad one by one:

  • page — the page containing the data for the pipe buffer. this is where the actual content lives. the whole point. the moment. ⭐
  • offset — offset of data inside the page. so, where in the page does the good stuff start? that's this. 📍
  • len — length of data inside the page. how much of it are we talking about. the size of the vibe check. 📏
  • ops — operations associated with this buffer. see pipe_buf_operations. this is the plug-in behaviour situation, iykyk. 🔥
  • flags — pipe buffer flags. see above. that's it, that's the note. 🙈
  • private — private data owned by the ops. hands off, it's theirs, it's personal. 💜

🌈 SEE ALSO 🌈

everything here lives in the kernel file ./include/linux/pipe_fs_i.h, and here's the whole friend group:

like, go read them, they're all slaying in their own way. 👑

and that's the page, bestie — love that for us. 💖

this came from ./include/linux, dated October 2026, and the title card says struct pipe_buffer(9). go off, kernel docs. periodt. 🧚✨
