✨ ixgbe_dbg_netdev_ops_write(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's called ixgbe_dbg_netdev_ops_write, and no cap, the whole personality of this function is: write into netdev_ops datum 🫶 that's it, that's the name section, we stan a straight-to-the-point icon.

🌸 SYNOPSIS 🌸

like, here's the whole signature, copy it exactly or the compiler will simply pass away 😭

ssize_t ixgbe_dbg_netdev_ops_write (struct file *filp , const char
       __user *buffer , size_t count , loff_t *ppos );

it returns a ssize_t, it's got four lil parameters, and honestly? it's giving "I take my job very seriously" energy ✨

💖 ARGUMENTS 💖

breaking down the friend group one by one, fr fr:

• filp — the opened file 👑 this is the actual file that somebody opened, and yeah, it's the one we're working with.
• buffer — where to find the user's data 🎀 the user's stuff lives out here in userspace, and this is the pointer that shows you where.
• count — the length of the user's data 🦋 so like, how much data is there? that number. it's this one.
• ppos — file position offset 📍 the whole "where are we in the file rn" situation. iconic. necessary. lowkey underrated.

a lil reminder bestie: filp is the opened file, buffer is where to find the user's data, count is the length of the user's data, and ppos is the file position offset — don't mix 'em up or it's gonna be a whole thing 🙈
