sqlite api programming question

Hello,

in the sqllite3.h file i found this definition.
"typedef struct sqlite3 sqlite3;"

And this function.

int sqlite3_open(
   const char *filename,   /* Database filename (UTF-8) */
   sqlite3 **ppDb          /* OUT: SQLite db handle */
);

How is the corresponding component pascal code for
sqlite3 **ppDB.

Thanks.
Helmut
