💖 VIORTC_MSG_WRITE 💖

okay bestie, welcome to the VIORTC_MSG_WRITE(9) page — yes that (9) means it's a kernel API thing, we're in the big leagues now, section 9, kernel developer land, very main character energy ✨

🌸 NAME 🌸

VIORTC_MSG_WRITE — it writes a request message field. that's the whole vibe. one job, does it well, slay 💅

🦋 SYNOPSIS 🦋

VIORTC_MSG_WRITE (hdl , dest_member , src_ptr );

literally the macro, the whole macro, and nothing but the macro. look at her go 🎀

🎀 ARGUMENTS 🎀

  • hdl — the message handle. your lil ticket to the message, the thing you're working on 🫶
  • dest_member — the request message field name. i.e. which field you're writing into, by name 🏷️
  • src_ptr — a pointer to data of compatible type. so like, pointer to the thing you want to shove in there. type has to match, no cap 🙈

⭐ DESCRIPTION ⭐

so what does it actually do? it writes the field in little-endian format. that's it. that's the tea ☕ little-endian, LSB first, the way the kernel likes it 💜

no secrets, no hidden options, no gotchas in the docs — just a field, written little-endian, periodt 🔥
