iucv_message_send2way(9)

💖 NAME 💖

okay bestie, this is literally iucv_message_send2way(9), straight from the Kernel API Manual, and I’m lowkey obsessed with how hard this name goes: transmits a two-way message ✨

• iucv_message_send2way — transmits a two-way message 💌

✨ SYNOPSIS ✨

       int iucv_message_send2way (struct iucv_path *path , struct iucv_message
       *msg , u8 flags , u32 srccls , void *buffer , size_t size , void *answer
       , size_t asize , size_t *residual );

🎀 ARGUMENTS 🎀

• path — address of the iucv path structure 🛤️
• msg — address of the iucv msg structure 💬
• flags — how the message is sent and the reply is received: IUCV_IPRMDATA, IUCV_IPBUFLST, IUCV_IPPRTY, IUCV_ANSLST 🚩
• srccls — source class of message 🏷️
• buffer — address of send buffer or address of struct iucv_array 📦
• size — length of send buffer 📏
• answer — address of answer buffer or address of struct iucv_array 💌
• asize — size of reply buffer 📬
• residual — ignored 🙈

not me pointing at residual and saying “ignored” — that’s literally what the page says, bestie. no cap, fr fr.

🦋 DESCRIPTION 🦋

okay so this function transmits data to another application. the data to be transmitted is in a buffer. the receiver of the send is expected to reply to the message, and a buffer is provided into which IUCV moves the reply to this message. it’s giving two-way message main character energy, periodt 💅

🌈 RETURN 🌈

vibe check says the return value is the result from the CP IUCV call. that’s it, that’s the tea ☕ iconic.
