NAME

memcmp - compare bytes in memory

 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 object pointed to by s1 to the first n bytes of the object pointed to by s2.

The sign of a non-zero return value is determined by the sign of the difference between the values of the first pair of bytes (both interpreted as type unsigned char) that differ in the objects being compared.

 RETURN VALUE

The memcmp() function returns an integer greater than, equal to or less than 0, if the object pointed to by s1 is greater than, equal to or less than the object pointed to by s2 respectively.
