imult64(3)

💖 NAME 💖

hey bestie, from the Library Functions Manual, meet imult64(3) — integer multiplication with overflow checking. she's the responsible friend who checks the math before anything goes feral. ✨

✨ SYNTAX ✨

#include <libowfat/safemult.h>

int imult64(int64 a,int64 b,int64* c);

🌸 DESCRIPTION 🌸

okay so imult64 does c=a*b, and then it returns 1. that's the whole main character move. 💅

but if there's an integer overflow? not on her watch. imult64 leaves c alone and returns 0. so c stays exactly how it was, no cap. 🫶

overflow check said: nope, we're not touching c, and we're returning 0. periodt. 👑
