Answer 1

if you system had been installed the Berkeley DB, you could use it like this, it is a demo to test, hope it could solve your problem:
#include <stdio.h>
#include <stdlib.h>
#include <db.h>
#define DATABASE "test.db"
typedef struct _data_struct {
int data_id;
char data[20];
} data_struct;
int main()
{
DBT key, data;
DB *dbp;
int ret;
data_struct my_data;
ret = db_create(&dbp, NULL, 0); // create the DB handle
if (ret != 0)
{
perror("create");
return 1;
}
ret = dbp->open(dbp, NULL, DATABASE, NULL, DB_BTREE, DB_CREATE, 0); // open the database
if (ret != 0)
{
perror("open");
return 1;
}
my_data.data_id = 1;
strcpy(my_data.data, "some data");
memset(&key, 0, sizeof(DBT));
memset(&data, 0, sizeof(DBT));
key.data = &(my_data.data_id);
key.size = sizeof(my_data.data_id);
data.data = &my_data;
data.size = sizeof(my_data);
ret = dbp->put(dbp, NULL, &key, &data, DB_NOOVERWRITE); // add the new data into the database
if (ret != 0)
{
printf("Data ID exists\n");
}
dbp->close(dbp, 0); // close the database
return 0;
}
