✨ cgiwrap_getenv(3) ✨

okay bestie, so this one lives in cgi/cgiwrap.h and it's part of ClearSilver — yes, that ClearSilver — and we're gonna talk about it 💖

🌸 NAME 🌸

cgiwrap_getenv — the wrapper for getenv 💅 (it's giving "middle management for environment variables", and honestly? we respect it)

🎀 SYNOPSIS 🎀

#include <cgi/cgiwrap.h>

NEOERR *cgiwrap_getenv (const char *k, char **v);

🦋 ARGUMENTS 🦋

• k — the environment variable you're tryna look up, bestie 🔍

💜 DESCRIPTION 💜

so cgiwrap_getenv wraps the getenv function for access to environment variables, which are used to pass data to CGI scripts 🌈. like, that's the whole vibe: env vars = the data pipe for CGI.

but here's the tea ☕ — this version differs from the system getenv in one major way: it makes a copy of the value it returns 📋✨. why do we care? because that gets around problems when you're wrapping this routine in garbage collected / reference counted languages, by moving the ownership of the data to the calling function 👑. so instead of handing you a pointer that might get yanked out from under you, it hands you your very own copy. main character energy, fr fr.

ngl, the copy thing is the entire point. that's the whole reason this wrapper exists. don't sleep on it 🫶

⭐ RETURN VALUE ⭐

• v — a newly allocated copy of the value of that variable, or NULL if not found 😭
