NAME
bcmp - compare byte string

LIBRARY
libc

SYNOPSIS
#include <strings.h>
int
bcmp(const void *b1, const void *b2, size_t len);

DESCRIPTION
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.
