ipc_imem_sys_cdev_write(9)

okay bestie, this is the ipc_imem_sys_cdev_write(9) page from the Kernel API Manual — and it's lowkey iconic because it's the one that routes the uplink buffer to CP. main character function behavior, honestly 💅✨

🌸 NAME 🌸

ipc_imem_sys_cdev_write — route the uplink buffer to CP. that's the whole quest, bestie: uplink buffer goes to CP 🫶

💖 SYNOPSIS 💖

here's the signature exactly as it appears, no edits, no cap:

       int ipc_imem_sys_cdev_write (struct iosm_cdev *ipc_cdev , struct sk_buff
       *skb );

🎀 ARGUMENTS 🎀

• ipc_cdev — an iosm_cdev instance. that's the iosm_cdev object you're passing in, periodt 💅
• skb — pointer to skb. literally a pointer to the skb, okay? 🦋

⭐ RETURN ⭐

0 on success, and a failure value on error. so if it works you get that clean 0; if it doesn't, you get a failure value 😭 no in-between drama.
