       Writes a new entry into database, which is defined in context. If context is NULL, the default database,
       defined in LL2_DEFAULT_DATABASE, will be taken.

           time_t login_time = time(0); // Get the system time
           char   *error = NULL;
           const  char *user = "root";

           int ret = ll2_write_entry (NULL, user, login_time, "pts/0",
                                       "192.168.122.1", NULL, &error);

       pam_service is the service or instance name which has generated the entry (optional).

       Returns 0 on success, -ENOMEM or -1 on other failure. error contains an error string if the return value
       is -1. error is not guaranteed to contain an error string, could also be NULL. error should be freed by
       the caller.
