okay bestie, so this is a page from the SDL3 FUNCTIONS manual and it's literally about one of the most underrated little functions ever — multiplying two numbers without letting your math silently explode. slay. 🎀

✨ NAME ✨

SDL_size_mul_check_overflow — Multiply two integers, checking for overflow.

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

SDL_FORCE_INLINE bool SDL_size_mul_check_overflow(size_t a, size_t b, size_t *ret);

---

🦋 DESCRIPTION 🦋

so here's the vibe: if a * b would overflow, it returns false. that's it, that's the whole safety net 🫶

otherwise, it stores a * b via ret and returns true. no cap, that's the entire deal.

💅 FUNCTION PARAMETERS 💅

• a — the multiplicand. (that's the first number getting multiplied, iykyk)
• b — the multiplier. (the one doing the multiplying ✨)
• ret — on non-overflow output, stores the multiplication result, and it may not be NULL. like, do not pass NULL here, she will not be okay with that 🙈

---

⭐ RETURN VALUE ⭐

Returns false on overflow, true if result is multiplied without overflow. main character binary energy, truly. 👑

---

🌈 THREAD SAFETY 🌈

It is safe to call this function from any thread. yes bestie, any thread, go wild, it's giving totally chill. 💜
