FEXECLE(3)

🌸 NAME 🌸

fexecle() — executes a program. That's it, that's the vibe: it executes a program, bestie. 🫶

✨ SYNOPSIS ✨

fexecle(name, in, out, err, a0, a1, a2, ... NULL, envptr)
char *name;
FILE *in, *out, *err;
char *a0, *a1, *a2...;
char **envptr;

💖 DESCRIPTION 💖

okay so fexecle() is a variation of fexecve(), and the description for fexecve() also applies to fexecle() — except for the argument list. No cap. ✨

The way that fexecle() works is it permits the argument list — which is a vector of pointers with a NULL at the end — to be constructed as part of the call to fexecle(), rather than as a C vector. It's giving "args built right into the call," and we're obsessed. 💅

Thus, in the new program, av[0] will be the same as a0 in this program, etc. Literally the same, periodt. 🎀

🎀 RETURNS 🎀

Returns a system error code; fexecle() does not return if it succeeds. So on success it just dips and never comes back — highkey iconic — and the return is a system error code. 💀
