MEMCMP(3) Linux Programmer's Manual MEMCMP(3) NAME
memcmp - compare memory areas SYNOPSIS
#include <string.h> int memcmp(const void *s1, const void *s2, size_t n); DESCRIPTION
The memcmp() function compares the first n bytes 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. RETURN VALUE
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. CONFORMING TO

MEMCMP(3) Linux Programmer's Manual MEMCMP(3) NAME
memcmp - compare memory areas SYNOPSIS
#include <string.h> int memcmp(const void *s1, const void *s2, size_t n); DESCRIPTION
The memcmp() function compares the first n bytes (each interpreted as unsigned char) of the memory areas s1 and s2. RETURN VALUE
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. For a nonzero return value, the sign is determined by the sign of the difference between the first pair of bytes (interpreted as unsigned char) that differ in s1 and s2. CONFORMING TO
