MEMCMP(3)MEMCMP(3)NAMEmemcmp - compare byte string
SYNOPSIS
#include <string.h>
int
memcmp(const void *b1, const void *b2, size_t len);
DESCRIPTION
Memcmp compares byte string b1 against byte string b2, returning zero
if they are identical, otherwise returning the difference between the
first two differing bytes (treated as unsigned char values, so that
'\200' is greater than '\0', e.g.). Both strings are assumed to be len
bytes long. Zero-length strings are always identical.
