FESETENV(3P)

💖 FESETENV(3P) 💖

okay bestie, real talk: this is a page from the POSIX Programmer's Manual — that's the manual this whole thing lives in. And it's a short one. Like, suspiciously short. But we're gonna make it cute anyway. 🎀

🌸 PROLOG 🌸

bestie listen, before you do anything:

• This page is part of the POSIX Programmer's Manual.
• The Linux implementation of this interface may differ — so go check the corresponding Linux manual page for the deets on Linux behavior.
• Or, plot twist: the interface might not even be implemented on Linux at all. 😭

So like… vibe check your platform first, okay? 🫶

💅 DESCRIPTION 💅

not me about to explain this one from scratch… no. this page is a redirect, babes:
