pipe_buf(9)

🌸 NAME 🌸

okay so bestie, we're flipping through the Kernel API Manual and the page is pipe_buf(9). It's giving very specific energy:

pipe_buf — Return the pipe buffer for the specified slot in the pipe ring. ✨

No cap, that's the function's whole deal. 💖

✨ SYNOPSIS ✨

struct pipe_buffer * pipe_buf (const struct pipe_inode_info *pipe ,
       unsigned int slot );

Lowkey iconic signature, right? It hands back a struct pipe_buffer *, takes a const struct pipe_inode_info *pipe, and asks for an unsigned int slot. 🎀

🎀 ARGUMENTS 🎀

• pipe — The pipe to access. That's the one you're poking at, bestie. 💅
• slot — The slot of interest. Like, which slot in the pipe ring has your attention? 👀
