The root directory is the prefix to which libalpm installs packages to.

Hooks and scriptlets will also be run in a chroot to ensure they behave correctly in alternative roots.

Returns the root path.

The dbpath is where libalpm stores the local db and downloads sync databases.

const char * alpm_option_get_dbpath (alpm_handle_t *handle)
Returns the path to the database directory.

The lockfile is used to ensure two instances of libalpm can not write to the database at the same time.

The lock file is created when committing a transaction and released when the transaction completes. Or when calling alpm_unlock.

const char * alpm_option_get_lockfile (alpm_handle_t *handle)
Get the name of the database lock file.

This is where libalpm will store downloaded packages.

Remove a cachedir from the configured cachedirs.

libalpm will search these directories for hooks to run.

A hook in a later directory will override previous hooks if they have the same name.

Sets the hookdirs.
int alpm_option_add_hookdir (alpm_handle_t *handle, const char *hookdir)
Append a hookdir to the configured hookdirs.
int alpm_option_remove_hookdir (alpm_handle_t *handle, const char *hookdir)
Remove a hookdir from the configured hookdirs.

Normally libalpm will refuse to install a package that owns files that are already on disk and not owned by that package.

If a conflicting file matches a glob in the overwrite_files list, then no conflict will be raised and libalpm will simply overwrite the file.

alpm_list_t * alpm_option_get_overwrite_files (alpm_handle_t *handle)
Gets the currently configured overwritable files,.

Returns the user to switch to for sensitive operations.
int alpm_option_set_sandboxuser (alpm_handle_t *handle, const char *sandboxuser)

This is effectively a list of virtual providers that packages can use to satisfy their dependencies.

alpm_list_t * alpm_option_get_assumeinstalled (alpm_handle_t *handle)
Gets the list of dependencies that are assumed to be met.
int alpm_option_add_assumeinstalled (alpm_handle_t *handle, const alpm_depend_t *dep)

libalpm will only install packages that match one of the configured architectures.

This controls the extension used for sync databases.

libalpm will use this extension to both lookup remote databases and as the name used when opening reading them.

This is useful for file databases. Seems as files can increase the size of a database by quite a lot, a server could hold a database without files under one extension, and another with files under another extension.

Which one is downloaded and used then depends on this setting.

const char * alpm_option_get_dbext (alpm_handle_t *handle)

By default, libalpm will timeout if a download has been transferring less than 1 byte for 10 seconds.

int alpm_option_set_disable_dl_timeout (alpm_handle_t *handle, unsigned short disable_dl_timeout)
Enables/disables the download timeout.

alpm_db_update, alpm_fetch_pkgurl and alpm_trans_commit can all download packages in parallel.

This setting configures how many packages can be downloaded in parallel,

By default this value is set to 1, meaning packages are downloading sequentially.

int alpm_option_get_parallel_downloads (alpm_handle_t *handle)
Gets the number of parallel streams to download database and package files.
int alpm_option_set_parallel_downloads (alpm_handle_t *handle, unsigned int num_streams)
Sets number of parallel streams to download database and package files.

By default, libalpm will sandbox the downloader process.
