💅 splice_from_pipe_begin(9)

okay so bestie, welcome to the Kernel API Manual — this one's a lil kernel function called splice_from_pipe_begin, and honestly? it's giving opening credits. 🎬 No cap.

✨ NAME ✨

splice_from_pipe_begin — start splicing from pipe 🫶

So like, the whole vibe is: you're kicking off a splice-from-pipe situation. This is the beginning. The main character entrance. 💫

🌸 SYNOPSIS 🌸

void splice_from_pipe_begin (struct splice_desc *sd );

Yeah it returns void, she doesn't do returns, she does vibes.

🎀 ARGUMENTS 🎀

  • sd — the struct splice_desc * holding all the info about the splice operation. literally the whole personality of the operation lives in here 💖

🦋 DESCRIPTION 🦋

okay so listen 👂 — this function should be called before a loop that contains splice_from_pipe_next and splice_from_pipe_feed. Why? because she's the one who initializes the necessary fields of sd. she sets the stage, she does the prep work, she gets sd ready for the loop to do its thing. ✨

it's giving "get ready with me" but for kernel structs. 🌈 the loop cannot slay if sd isn't initialized first, iykyk.

💀 fr fr: call splice_from_pipe_begin first. before the loop. not during, not after. bestie the ordering is the whole point.
