BCMP(9)

💖 BCMP(9) 💖

hey bestie, welcome to this page from the Kernel Developer's Manual — it's all about BCMP(9), aka byte-string comparing, but make it vintage 👑

---

✨ NAME ✨

bcmp — compare byte string 🫶

---

🌸 SYNOPSIS 🌸

#include <sys/systm.h>

int
bcmp(const void *b1, const void *b2, size_t len);

---

🫶 DESCRIPTION 🫶

okay so real talk: the bcmp() interface is obsolete. Do not add new code using it. It will soon be purged. Use memcmp(9) instead. (The bcmp() function is now a macro for memcmp(9).) 💀

The bcmp() function compares byte string b1 against byte string b2, returning zero if they are identical, non-zero otherwise. Both strings are assumed to be len bytes long. Zero-length strings are always identical. ✨

The strings may overlap. 🌀
