PROLOG

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 inter-
       preted 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.

ERRORS
