✨ NAME ✨

dvb_ca_en50221_io_write — Implementation of write() syscall. 🎀 that's it. that's the function. she writes.

🌸 SYNOPSIS 🌸

ssize_t dvb_ca_en50221_io_write (struct file *file , const char __user
*buf , size_t count , loff_t *ppos );

like, look at her. signature so clean. ngl the line break in the middle of the parameter list is giving "typeset by a manpage gremlin" but we respect it 💀

🦋 ARGUMENTS 🦋

  • file — File structure. that's the file, bestie. she's the object. 👑
  • buf — Source buffer. the place the bytes are coming from. 🍓
  • count — Size of source buffer. how many bytes we're working with, fr fr. 🔥
  • ppos — Position in file (ignored). ignored!! she literally does not care about your position. main character energy of not reading the room 🙈

⭐ RETURN ⭐

Number of bytes read, or <0 on error. 💀 yes the original says "bytes read" for a write function — I'm not fixing it, I'm just reporting it, and honestly? iconic. periodt. ✨

reminder bestie: <0 means something went wrong. don't ignore the negative numbers, they're literally screaming at you 😭
