 * NAME
 *      strcmp, strncmp - compare two strings
 *
 * SYNOPSIS
 *      #include <string.h>
 *
 *      int strcmp(const char *s1, const char *s2);
 *
 *      int strncmp(const char *s1, const char *s2, size_t n);
 *
 * DESCRIPTION
 *      The  strcmp()  function compares the two strings s1 and s2.  
 *      The locale is not taken into account (for a locale-aware comparison, see strcoll(3)).  
 *      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 strncmp() function is similar, except it compares only the first (at most) n bytes of s1 and s2.
 *
 * RETURN VALUE
 *      The strcmp() and strncmp() functions return an integer less than, equal to, or greater than zero 
 *      if s1 (or the first n bytes thereof) is found, respectively, to be less than,  to  match, or be greater than s2.
