Try this, it's the db_stat which is wrong, the database is correctly
created as DB_HASH.
int main(int argc, char **argv)
{
int envflags = DB_INIT_TXN | DB_INIT_MPOOL;
int flags = DB_RDONLY | DB_AUTO_COMMIT;
DB_ENV *dbenv;
DBTYPE type;
DB *dbp;
const char *filename = argv[1];
if (argc < 2)
return 2;
mkdir(filename, 0700);
db_env_create(&dbenv, 0);
dbenv->open(dbenv, filename, envflags, 0700);
db_create(&dbp, dbenv, 0);
dbp->open(dbp, NULL, "openpgp", "openpgp", DB_UNKNOWN, flags,
0600);
dbp->get_type(dbp, &type);
if (type == DB_HASH) {
printf("DB Type is DB_HASH\n");
} else {
printf("DB Type is not DB_HASH\n");
}
dbp->close(dbp, 0);
dbenv->close(dbenv, 0);
return 0;
}
