💖 umult16(3) — Library Functions Manual 💖

okay bestie, listen up, because this one is short but it's lowkey a lifesaver 🫶 it lives in the Library Functions Manual and it's giving "tiny function, huge main character energy" ✨

🌸 NAME 🌸

umult16 — integer multiplication with overflow checking 💅

🎀 SYNTAX 🎀

#include <libowfat/safemult.h>

int umult16(uint16 a,uint16 b,uint16* c);

no cap, that's the whole vibe. two numbers in, one pointer out 🌈

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — umult16 does c=a*b and returns 1. that's it. that's the function. it multiplied. it slayed. periodt 💅✨

but wait, there's more, because this is the safe one 🧚

In case of an integer overflow, umult16 leaves c alone and returns 0. 😭

so like, if the math would blow past what fits, it does not touch your c, it does not pretend everything's fine, it just quietly returns 0 and lets you handle it. no silent chaos. no undefined nonsense. just honesty 💖 that's the whole point of the safemult header — it's the friend who tells you when you've had enough 🍓

so: return value 1 = you ate. return value 0 = overflow, c is untouched, try again with a bigger type maybe 👑
