📦 version 7.3.1, in nixpkgs unstable

💅 ksmbd_vfs_read(9) — like, the vfs helper for smb file read, bestie

okay so this is ksmbd_vfs_read(9) from the Kernel API Manual, and before you panic: it's just the vfs helper for smb file read. that's the whole vibe. one little function that goes and grabs bytes off a file for you. iconic, honestly. 🎀

✨ NAME ✨

ksmbd_vfs_read — the vfs helper for smb file read 🫶

🌸 SYNOPSIS 🌸

int ksmbd_vfs_read (struct ksmbd_work *work , struct ksmbd_file *fp ,
       size_t count , loff_t *pos , char *rbuf );

🦋 ARGUMENTS 🦋

bestie there are five (5) of them, and yes you have to give all of them. no skipping, that's not the move. 💀

  • work — the smb work 💼 (your main character struct, the thing doing the work)
  • fp — the ksmbd file pointer 📁 (which file we're reading from, obviously)
  • count — read byte count 🔢 (how many bytes we're grabbing, literally)
  • pos — file pos 📍 (where in the file we're at — it's a pointer, so it can move, iykyk)
  • rbuf — read data buffer 🧺 (the spot where the data lands so you can actually use it)
ngl, pos being a loff_t * instead of a plain value is giving "I will update your position" energy. keep that in mind. ✨

🔥 RETURN 🔥

number of read bytes on success 🎉 — otherwise, an error 😭. that's it, that's the contract. slay.
