the sqlite3_close() <--- needs one argument if i pass sqlite3_close(NULL) it
actually closes again a closed connection ?
I cant find if the certain sqlite3 *ppDB is open or closed :/
if(ppDB){
//is open
}else{
//is closed
}
It returns always that the ppDB is open in the above function

sqlite3_close() ignores connections which are already closed. If you call it
and pass it null, it will return, doing nothing but returning no error message.
So it is safe to issue sqlite3_close() on one connection.
