FEXECVE(3POSIX)

💖 FEXECVE(3POSIX) 💖

okay bestie, welcome to the POSIX Programmer's Manual ✨ this one's a lil baby page but it's iconic in its own way. it's fexecve from section 3, and yes we're gonna read it together, no skimming, no cap 🫶

🌸 PROLOG 🌸

okay so first things first, a lil heads up before we get into it:

this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ — so like, consult the corresponding Linux manual page for details of Linux behavior, okay? — or honestly the interface may not be implemented on Linux at all. 💀 so vibe check your platform first, fr fr.

✨ NAME ✨

fexecve — execute a file 🏃♀️💨

🎀 SYNOPSIS 🎀

here's the shape of it, bestie:

#include <unistd.h>

int fexecve(int fd, char *const argv[], char *const envp[]);

yes the argument types are exactly that, don't get creative with them 💅

🦋 DESCRIPTION 🦋

okay so the whole description here is literally just: Refer to exec.

that's it. that's the vibe. this page is a lil signpost pointing you at exec for the actual deets, so go read that one, i promise it's worth it 🥰
