SDL_zeroa(3)

💖 SDL_zeroa 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where we're talking about SDL_zeroa — the macro that wipes an array's memory squeaky clean to zero ✨

---

🌸 NAME 🌸

SDL_zeroa — clear an array's memory to zero. that's it, that's the whole job, and she does it flawlessly 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_stdinc.h>

#define SDL_zeroa(x) SDL_memset((x), 0, sizeof((x)))

---

🦋 DESCRIPTION 🦋

so like, this is a wrapper over SDL_memset that handles calculating the array size for you 🫶 which means there's no chance of copy/paste errors, and honestly? the code is just cleaner. it's giving responsible coding, it's giving main character energy.

⚠️ but listen — this requires an array, not an object, and not a pointer to an object. she's specific about that, okay? no cap.

---
