💖 iucv_send_iprm(9) 💖

okay bestie, welcome to the Kernel API Manual entry for iucv_send_iprm — yes, it's a whole function, and yes, it's kind of iconic. we're sending socket data in the parameter list of an iucv message. periodt. 🫶

🌸 NAME 🌸

iucv_send_iprm — Send socket data in parameter list of an iucv message. literally that. 💅

✨ SYNOPSIS ✨

       int iucv_send_iprm (struct iucv_path *path , struct iucv_message *msg ,
       struct sk_buff *skb );

🎀 ARGUMENTS 🎀

• path — IUCV path. yes bestie, the path. 🛣️
• msg — Pointer to a struct iucv_message. pointer agenda, we love to see it. 💖
• skb — The socket data to send, and listen: skb->len MUST BE <= 7. not "probably", not "if you feel like it" — MUST BE. lowkey crucial. 🚨

💫 DESCRIPTION 💫

so the function sends the socket data in the parameter list in the iucv message (IUCV_IPRMDATA). the socket data is stored at index 0 to 6 in the parameter list, and the socket data len is at index 7 (the last byte). See also iucv_msg_length. that's the whole vibe. ✨

bestie, skb->len being <= 7 is not a suggestion. that's the requirement. do not test it. 😭

🔥 RETURN 🔥

the return code from the iucv_message_send call. that's it, that's the return. 👑
