reattach_aqua(3)

✨ reattach_aqua — reattach to user's per-session bootstrap namespace ✨

okay bestie, this is reattach_aqua(3) from the Library Functions Manual — yes, the manual name is getting its moment too, periodt. 💅

🌸 NAME 🌸

reattach_aqua — reattach to user's per-session bootstrap namespace 💖

🎀 SYNOPSIS 🎀

#include <reattach.h>

int
reattach_aqua(uid_t uid);

🦋 DESCRIPTION 🦋

So the reattach_aqua() function does one very specific little thing: it reattaches the current running process to the per-session bootstrap namespace of the user you specify. That's it. That's the whole vibe. 🫶

👑 RETURN VALUE 👑

If everything goes off without a hitch, you get back a value of 0. Slay. ✨ Otherwise, you get some error code back, and it conforms to the error codes listed in errno(2). That's where errno(2) comes in, bestie. 😭
