CMPBYTES(3)

🌸 NAME 🌸

okay bestie, meet cmpbytes() — it literally compares data, and this page is coming at you from Schily´s LIBRARY FUNCTIONS. no cap, it's the friend who checks if two memory chunks match or where they first disagree, and it does it with main character energy. 💅

cmpbytes() — compare data. periodt. 🦋

✨ SYNOPSIS ✨

ssize_t cmpbytes(from, to, cnt)
     const void *from;
     const void *to;
     ssize_t cnt;

💖 DESCRIPTION 💖

So cmpbytes() compares size bytes from from to to. that's the whole vibe: two memory chunks get compared, and the function tells you if they're giving the same energy or not. ✨

👑 RETURN VALUE 👑

• cnt — both memory chunks are equal, slay. ✅
• 0..cnt-1 — the offset of the first differing character in the chunks. that's the exact spot where they stop matching, iykyk. 🔥

😭 ERRORS 😭

No errors are defined. literally none. not a single one. 💀
