splice_to_socket(9)
π splice_to_socket(9) β the kernel API glow-up you didn't know you needed β¨
Okay bestie, listen. This is the splice_to_socket(9) page from the Kernel API Manual, and it's literally about moving data from a pipe to a socket with zero copying involved. No cap, that's the whole vibe. Let's get into it π«Ά
β¨ NAME β¨
splice_to_socket β splice data from a pipe to a socket π
πΈ SYNOPSIS πΈ
ssize_t splice_to_socket (struct pipe_inode_info *pipe , struct file
*out , loff_t *ppos , size_t len , unsigned int flags );
π¦ ARGUMENTS π¦
pipeβ the pipe you're splicing from, aka the source. Your starting point, your origin story πoutβ the socket you're writing to. The destination. The main character of this operation πpposβ position inout. Where you're at in the file, tracking your journey fr frlenβ number of bytes to splice. The amount of data making the move πflagsβ splice modifier flags. The little settings that tweak how it all goes down β¨
π DESCRIPTION π
So basically, this will send len bytes from the pipe to a network socket. And the iconic part? No data copying is involved. Zero. None. Not me being dramatic, it's just that efficient. The data literally just vibes its way over there without being duplicated and we're obsessed π
