💅 comp_write — Kernel API Manual ✨

Ok bestie, welcome to comp_write(9) — the Kernel API Manual page that's lowkey all about the syscall side of writing to the device. Periodt. 🫶

🌸 NAME

comp_write — implements the syscall to write to the device 💖

✨ SYNOPSIS

ssize_t comp_write (struct file *filp , const char __user *buf , size_t
       count , loff_t *offset );

🎀 ARGUMENTS

• filp — file pointer. The whole file-hookup situation. 📁
• buf — pointer to user buffer. This is where the bytes are coming from, bestie. 🧺
• count — number of bytes to write. Exactly how many, no cap. 🔢
• offset — offset from where to start writing. The starting point, the vibe check location. 📍

🦋 SEE ALSO

• Kernel file ./drivers/most/most_cdev.c — yes, the whole file, iconic. 💅
• comp_open(9)
• comp_close(9)
• comp_read(9)
• comp_disconnect_channel(9)
• comp_rx_completion(9)
• comp_tx_completion(9)

Bestie, that's the whole page. All the flags, args, and references are right here — no crumbs left behind. 🍓

Sign-off vibes: this one comes from ./drivers/most, dated October 2026, and it's literally comp_write(9) in the Kernel API Manual. Slay. 👑💜
