           }

        /* This program checks the wcsrchr function by searching for */
        /* the last occurrence of a string in the buffer s1buf and   */
        /* prints out the contents of s1buff from the location of
        /* the string found.                                         */

            status = wcsrchr(s1buf, w_string[0]);
        /* Check for pointer to start of rightmost character string. */
            if (status == pbuf) {
                printf("Error in wcsrchr\n");
                exit(EXIT_FAILURE);
            }

            printf("Program completed successfully\n");
            printf("String found : [%S]\n", status);

        }

      Running the example produces the following result:

        Program completed successfully
        String found : [hijklfedcba]
