llc_ui_recvmsg(9)

🎀 NAME 🎀

okay so we're in the Kernel API Manual, and this page is all about llc_ui_recvmsg(9) — the function whose whole thing is: copy received data to the socket user. slay.

✨ SYNOPSIS ✨

int llc_ui_recvmsg (struct socket *sock , struct msghdr *msg , size_t
len , int flags );

💅 ARGUMENTS 💅

• sock — the socket you're copying data from. that's the source, bestie.
• msg — "various user space related information" — literally the user-space info bundle.
• len — size of the user buffer. how much room we're working with.
• flags — user-specified flags. the user said what they said.

🌸 DESCRIPTION 🌸

okay so the function does exactly what it says on the tin: copy received data to the socket user. no cap. Returns non-negative upon success, negative otherwise. that's the whole vibe check: non-negative = good, negative = not it.
