splice_from_pipe(9)

📦 version 7.3.1, in nixpkgs unstable

💅 splice_from_pipe — bestie, it's a kernel function ✨

okay so this is splice_from_pipe(9) from the Kernel API Manual, and no cap it's lowkey iconic. it moves data from a pipe into a file. that's the whole vibe. let's get into it 🫶

✨ NAME ✨

splice_from_pipe — splice data from a pipe to a file

like literally what it says on the tin, bestie. pipe in, file out. slay. 🌈

🦋 SYNOPSIS 🦋

ssize_t splice_from_pipe (struct pipe_inode_info *pipe , struct file
*out , loff_t *ppos , size_t len , unsigned int flags , splice_actor
*actor );

six whole arguments, she's that girl. returns an ssize_t because of course she does 💅

🎀 ARGUMENTS 🎀

  • pipe — the pipe to splice from. this is the source, the main character, the origin story 🌸
  • out — the file to splice to. the destination. the moment. the glow-up 🦋
  • ppos — position in out. it's a pointer to a loff_t, so like, she knows exactly where she is 💖
  • len — how many bytes to splice. yes, that's the number of bytes. very demure, very mindful 🎀
  • flags — splice modifier flags, unsigned int flavored. little toggles, big energy ✨
  • actor — handler that splices the data. this one does the actual work, she's the splice_actor *, the icon, the legend 👑

🔥 DESCRIPTION 🔥

okay so the manual is being mysterious and just says: see __splice_from_pipe. iykyk. 💀

the one (1) difference, and this is the important part so listen up: this function locks the pipe inode. otherwise it's literally identical to __splice_from_pipe. like twins. same function energy, just with a lock. fr fr 🫶

no cap, the only delta here is the inode lock — everything else? identical to __splice_from_pipe.

👑 SEE ALSO 👑

Kernel file ./fs/splice.c and honestly the whole splice friend group showed up for this one:

the way that's thirteen whole entries 😭 the whole squad, all in ./fs/splice.c. go read them. periodt. 💜

anyway bestie, that's the whole page 💖 this one came to you from the source ./fs, dated October 2026, and yes — she's still splice_from_pipe(9) in the Kernel API Manual. mwah, go splice something 🌸✨🎀
