- *
- * A transaction is necessary for this operation, in order to obtain a

- * of the download progress of the database via the download callback.
- *
- * Example:
- * @code
- * pmdb_t *db;
- * int result;
- * db = alpm_list_getdata(alpm_option_get_syncdbs());
- * if(alpm_trans_init(0, NULL, NULL, NULL) == 0) {

- * }
- * @endcode
- *
- * @ingroup alpm_databases
- * @note After a successful update, the \link alpm_db_get_pkgcache()

- * @param force if true, then forces the update, otherwise update only in case
