sqlite binding

[Ching Bon Lam <c.lam_REMOVE_THIS@student.utwente.nl>]

hello everyone,

I've been trying to make some sort of sqlite binding. SQLite itself is at 
http://www.sqlite.org/ . For now i just want to import the core api 
consisting of three functions (taken from sqlite.h):

-- Code -----------------------------------------------------------------

sqlite *sqlite_open(const char *filename, int mode, char **errmsg);

void sqlite_close(sqlite *);

int sqlite_exec(
  sqlite*,          /* An open database */
  const char *sql,  /* SQL to be executed */
  sqlite_callback,  /* Callback function */
  void *,           /* 1st argument to callback function */
  char **errmsg     /* Error msg written here */
);

-------------------------------------------------------------------------

with:

-- Code -----------------------------------------------------------------

typedef struct sqlite sqlite; /* opaque struct */
typedef int (*sqlite_callback)(void*,int,char**, char**);

-------------------------------------------------------------------------

What I did till now is:

-- Code -----------------------------------------------------------------

-- typedef struct sqlite sqlite; /* opaque struct */
subtype sqlite is Interfaces.C.Extensions.opaque_structure_def;

-------------------------------------------------------------------------

i don't know how to do the rest with the tons of pointers as arguments..
if someone would give me some pointers/guidance/hints, i would be really 
grateful.

greetings,
CBL
