LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <strings.h>
int
bcmp(const void *b1, const void *b2, size_t len);

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.
