ipc_parse_version(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ipc_parse_version — like, the ipc call version, bestie ✨

okay so welcome to ipc_parse_version(9), straight out of the Kernel API Manual 🎀 — this is the little function that looks at a SysV IPC command and is like "bestie… are you old-style or new-style?" and then tells you. iconic behavior, honestly.

🌸 NAME 🌸

ipc_parse_version — literally the ipc call version 🫶

✨ SYNOPSIS ✨

int ipc_parse_version (int *cmd );

that's it. one function, one pointer, absolutely no drama 💅

🦋 ARGUMENTS 🦋

  • cmd — a pointer to the command 💖 (yes, a pointer, ngl she's just pointing at your command and peeking at it)

🔥 DESCRIPTION 🔥

so here's the tea ☕: ipc_parse_version returns IPC_64 when you're dealing with new style IPC, and IPC_OLD when it's old style IPC. two eras, one vibe check ✨

and the glow-up? the cmd value gets turned from an encoding command and version situation into just the command code — like she stripped the outfit down to the main character fit 👑

so you hand her the encoded thing, she hands you back the plain command code, and she also tells you which era it came from. multitasking queen 👑💖
