[uuid(06a12100-2d26-11c9-aa24-08002b0ecef1)]
interface phonedir
{
typedef struct
{
short int area_code;
long int phone_num;
char last_name[20];
char first_name[15];
char city[20];
} dir_t;
void add ([in] dir_t *info);
void lookup ([in] char city[20],
[in] char last_name[20],
[in] char first_name[15],
[out] dir_t *info);
void delete ([in] dir_t *info);
}
