memcmp - compare memory areas
int memcmp(const void *s1, const void *s2, size_t n);
The memcmp() function compares the first n bytes (each interpreted as
unsigned char) of the memory areas s1 and s2. It returns an integer
less than, equal to, or greater than zero if s1 is found, respectively,
to be less than, to match, or be greater than s2.
The memcmp() function returns an integer less than, equal to, or
greater than zero if the first n bytes of s1 is found, respectively, to
be less than, to match, or be greater than the first n bytes of s2.
