Example

       #include <stdlib.h>
       #include <stdio.h>
       #include <wchar.h>
       #include <string.h>

       #define BUFF_SIZE 50
       #define STRING_SIZE 6

       main()
       {
           int i;
           wchar_t s1buf[BUFF_SIZE],
                   w_string[STRING_SIZE];
           wchar_t *status;
           wchar_t *pbuf = s1buf;

           /* Initialize the buffer */

           if (mbstowcs(s1buf, "hijklabcdefg ytuhijklfedcba", BUFF_SIZE)

               == (size_t)-1) {

               perror("mbstowcs");
               exit(EXIT_FAILURE);
           }

           /* Initialize the string to be searched for */

           if (mbstowcs(w_string, "hijkl", STRING_SIZE) == (size_t)-1) {

               perror("mbstowcs");
               exit(EXIT_FAILURE);
          }

       /* 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]
