🎀 NAME 🎀

Okay so array3_size(9) from the Kernel API Manual is literally here to Calculate size of 3-dimensional array. 💖 Bestie, that's the whole vibe: three dimensions, one size calculation.

✨ SYNOPSIS ✨

The signature is giving exactly this:

size_t array3_size (size_t a , size_t b , size_t c );

💅 ARGUMENTS 💅

Three lil inputs, one per dimension — iconic:

• a — dimension one
• b — dimension two
• c — dimension three

🌸 DESCRIPTION 🌸

It's literally doing this: Calculates size of 3-dimensional array: a * b * c. That's the math, and it ate. 🧮✨

🦋 RETURN 🦋

You get back the number of bytes needed to represent the array, or SIZE_MAX on overflow. No cap — overflow means SIZE_MAX, periodt. 💀
