# NAME

`bcmp` —
compare byte string

# SYNOPSIS

`#include <sys/systm.h>`

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

# DESCRIPTION

The `bcmp`() interface is obsolete.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.
