✨ pipe_buf_get(9) ✨ — Kernel API Manual energy

okay so welcome to the Kernel API Manual, bestie 💖 today’s main character is pipe_buf_get(9), and she is here to get you a reference to a pipe_buffer. That’s the whole vibe. Let’s get into it 🎀

---

🌸 NAME 🌸

pipe_buf_get — get a reference to a pipe_buffer

Like, the function name is literally doing what it says on the label. Obsessed. 💅

---

✨ SYNOPSIS ✨

bool pipe_buf_get (struct pipe_inode_info *pipe , struct pipe_buffer *buf );

That signature is giving “small function, big responsibility,” fr fr 🌈

---

🎀 ARGUMENTS 🎀

• pipe — the pipe that the buffer belongs to. The pipe is the home base, iykyk 🫶
• buf — the buffer to get a reference to. This is the little guy in question 💖

---

💖 RETURN 💖

true if the reference was successfully obtained.

No cap, that’s the return value. If it worked, you get true. Periodt. ✨
