SDL_unsetenv_unsafe(3)

💖 SDL_unsetenv_unsafe(3) 💖

okay bestie, welcome to the SDL3 functions era of the manual pages, we're doing SDL_unsetenv_unsafe today and honestly? it's giving "delete but make it spicy" 🎀

---

✨ NAME ✨

SDL_unsetenv_unsafe — clear a variable from the environment. yeah. that's the whole job. she removes one (1) env var and she does not overthink it 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

int SDL_unsetenv_unsafe(const char *name);

---

🦋 FUNCTION PARAMETERS 🦋

• name — the name of the variable you want to unset. like, the actual string of the variable's name. that's it, that's the vibe 🫶

---

⭐ RETURN VALUE ⭐

• 0 — slay, it worked, success 💖
• -1 — nope, error, something went wrong 😭

---

💀 THREAD SAFETY 💀

not thread safe. like, do NOT be out here calling this from multiple threads at once, that's main character behavior in the worst way 🙈

the page literally says: consider using SDL_UnsetEnvironmentVariable() instead. so bestie, if you're threading, go there instead, fr fr.

---

🌈 AVAILABILITY 🌈

this one's been around since SDL 3.2.0. vintage-ish. iconic. 👑
