LRAND48(3POSIX)

💖 LRAND48 — ok bestie, it's giving random numbers 💖

This page is part of the POSIX Programmer's Manual, and it's LRAND48(3POSIX), and we're doing this. 🫶

Heads up bestie, real talk: the Linux implementation of this interface may differ (so go check the corresponding Linux manual page for the details of Linux behavior), or honestly the interface may not be implemented on Linux at all. 🙈

✨ PROLOG ✨

Okay so first thing, before we get into it — this manual page is part of the POSIX Programmer's Manual. That's the whole vibe.

But like… the Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. So don't come for me if it's not there, okay? 😭

🌸 NAME 🌸

lrand48 — generate uniformly distributed pseudo-random non-negative long integers

Yes she generates. Yes they're uniform. Yes they're non-negative. Yes they're longs. Queen behavior fr fr. 👑

🎀 SYNOPSIS 🎀

#include <stdlib.h>

long lrand48(void);

That's it. That's the whole signature. No arguments, no drama, just vibes and a long. ✨

Refer to drand48().

(Yeah that's literally the whole description. It's giving "go ask her sister". Go read drand48() bestie, that's where the lore lives. 💅)
