Here is the caller graph for this function:

int alpm_db_update	(	int	force,
		alpm_db_t *	db
	)

Update a package database.

An update of the package database db will be attempted. Unless force is true, the update will only be performed if the remote database was modified since the last update.

This operation requires a database lock, and will return an applicable error if the lock could not be obtained.

Example:

 alpm_list_t *syncs = alpm_option_get_syncdbs();
 for(i = syncs; i; i = alpm_list_next(i)) {
     alpm_db_t *db = alpm_list_getdata(i);
     result = alpm_db_update(0, db);

     if(result < 0) {
           printf("Unable to update database: %s\n", alpm_strerrorlast());
     } else if(result == 1) {
         printf("Database already up to date\n");
     } else {
         printf("Database updated\n");
     }
 }

Note:: After a successful update, the package cache will be invalidated

Parameters:

force	if true, then forces the update, otherwise update only in case the database isn't up to date
db	pointer to the package database to update

Returns:: 0 on success, -1 on error (pm_errno is set accordingly), 1 if up to to date
