-/** Update a package database
- *
- * An update of the package database \a db will be attempted. Unless
- * \a force is true, the update will only be performed if the remote
- * database was modified since the last update.
- *
- * A transaction is necessary for this operation, in order to obtain a
- * database lock. During this transaction the front-end will be informed
- * 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) {
- * result = alpm_db_update(0, db);
- * alpm_trans_release();
- *
- * if(result > 0) {
- * printf("Unable to update database: %s\n", alpm_strerrorlast());
- * } else if(result < 0) {
- * printf("Database already up to date\n");
- * } else {
- * printf("Database updated\n");
- * }
- * }
- * @endcode
- *
- * @ingroup alpm_databases
- * @note After a successful update, the \link alpm_db_get_pkgcache()
- * package cache \endlink will be invalidated
- * @param force if true, then forces the update, otherwise update only in case
- * the database isn't up to date
- * @param db pointer to the package database to update
- * @return 0 on success, > 0 on error (pm_errno is set accordingly), < 0 if up
- * to date
