NAME

       strncmp - compare part of two strings

SYNOPSIS

       #include <string.h>

       int strncmp(const char *s1, const char *s2, size_t n);

DESCRIPTION

       The  strncmp()  function  shall  compare  not  more  than  n bytes (bytes that follow a null byte are not
       compared) from the array pointed to by s1 to the array 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 strings being compared.

RETURN VALUE

       Upon successful completion, strncmp() shall return an integer greater than, equal to, or less than 0,  if
       the  possibly null-terminated array pointed to by s1 is greater than, equal to, or less than the possibly
       null-terminated array pointed to by s2 respectively.
