Examples

   1.#include <string.h>

     #include <stdio.h>

     main()
     {
         printf( "%d\n", strncmp("abcde", "abc", 3));
     }

     When linked and executed, this example returns 0, because the
     first 3 characters of the 2 strings are equal:

       $ run tmp
       0

   2.#include <string.h>

     #include <stdio.h>

         main()
         {
             printf( "%d\n", strncmp("abcde", "abc", 4));
         }

     When linked and executed, this example returns a value greater
     than 0 because the first 4 characters of the 2 strings are not
     equal (The "d" in the first string is not equal to the null
     character in the second):

       $ run tmp
               100
