   1.#include <stdio.h>

     #include <string.h>

     main()
     {
         static char str[] = "...ab..cd,,ef.hi";

         printf("|%s|\n", strtok(str, "."));
         printf("|%s|\n", strtok(NULL, ","));
         printf("|%s|\n", strtok(NULL, ",."));
         printf("|%s|\n", strtok(NULL, ",."));
     }

     Running this example program produces the following results:

       $ RUN STRTOK_EXAMPLE1
       |ab|
       |.cd|
       |ef|
       |hi|
       $

     #include <string.h>

     main()
     {
        char *ptr,
             string[30];

        /* The first character not in the string "-" is "A".  The   */
        /* token ends at "C.                                        */

         strcpy(string, "ABC");
         ptr = strtok(string, "-");
         printf("|%s|\n", ptr);

         /* Returns NULL because no characters not in separator      */
         /* string "-" were found (i.e.  only separator characters   */
         /* were found)                                              */

         strcpy(string, "-");
         ptr = strtok(string, "-");
         if (ptr == NULL)
             printf("ptr is NULL\n");

     }

     Running this example program produces the following results:

       $ RUN STRTOK_EXAMPLE2
       |abc|
       ptr is NULL
       $
