   This example returns a pointer to the first occurrence in the                
   array string of either a or b.

   char *result, *string = "A Blue Danube";                                     
   char *chars = "ab";                                                          
                                                                                
   result = strpbrk(string, chars);                                             
   printf("The first occurrence of any of the characters \"%s\" in "            
          "\"%s\" is \"%s\"\n", chars, string, result);
