GETUDENT(3)

✨ GETUDENT(3) ✨

okay bestie, welcome to the UNIDATA LIBRARY FUNCTIONS corner of the manual, this one's the GETUDENT page and it's short but it's cute, let's go 💖

🌸 NAME 🌸

getuduser — bestie, this one's job is to hand you back the user database entry of a Unidata user. that's it. that's the whole vibe. 🫶

🎀 SYNOPSIS 🎀

#include <unistd.h>

const struct passwd *getudent(void);

like, no arguments, no drama, she just returns ✨

💅 DESCRIPTION 💅

so here's the tea, bestie 🍓 — this function returns the user database entry for the Unidata user, or NULL if no such user exists. like if she can't find them, she's not gonna fake it, she's just gonna hand you a NULL and walk away 💀

the way she finds them? she tries the UNIX function getpwnam() with a whole series of user names, and she stops at the first valid entry. first one to hit, wins. periodt. 👑

the first name she tries is the value of the environment variable UDLOGNAME, if it exists. (if it doesn't exist, she's not even gonna look, she just moves on, nbd)

the remaining names she tries are, in order:

1. "unidata"
2. "ldm4"
3. "ldm"

so it's giving very much "i have a list and i'm gonna work through it" energy 📋✨ and she stops the second one of them is valid, no cap.

🌈 ENVIRONMENT 🌈

• UDLOGNAME — contains the name of the Unidata user. this one gets tried first, so if you set it, you're basically the main character of the lookup 👑💜
