v9fs_create(9)

📦 version 7.3.1, in nixpkgs unstable

💅 v9fs_create(9) — the Kernel API Manual page you've been waiting for

okay so bestie, welcome to the kernel API manual, section 9, and today's main character is v9fs_create ✨ this one's a kernel function, so grab your iced coffee and let's get into it 🫶

🌸 NAME 🌸

v9fs_create — literally just: Create a file 🎀 that's the whole name section, no notes, iconic behavior honestly.

✨ SYNOPSIS ✨

struct p9_fid * v9fs_create (struct v9fs_session_info *v9ses , struct
inode *dir , struct dentry *dentry , char *extension , u32 perm , u8
mode );

like, it hands you back a struct p9_fid * and it takes six whole arguments — she's high maintenance but she's worth it 💖

🦋 ARGUMENTS 🦋

  • v9ses — the session information. the vibe check of the session, if you will 🌈
  • dir — the directory that dentry is being created in. it's the location, the venue, the address 👑
  • dentry — the dentry that's being created. that's the baby. the new one. the whole point 🥹
  • extension — the 9p2000.u extension string to support devices, etc. etc. is doing a LOT of heavy lifting in that sentence but okay go off 🧚
  • perm — create permissions 💅
  • mode — open mode ⭐
ngl bestie, these argument descriptions are giving "the man page was in a hurry" but I promised to keep every detail so here we are 😭
