Commit a transaction. @param handle the context handle @param data the address of an alpm_list where detailed description of an error can be dumped (i.e. list of conflicting files) @return 0 on success, -1 on error (pm_errno is set accordingly)

Returns a list of packages added by the transaction. @param handle the context handle @return a list of alpm_pkg_t structures

Returns the bitfield of flags for the current transaction. @param handle the context handle @return the bitfield of transaction flags

Returns the list of packages removed by the transaction. @param handle the context handle @return a list of alpm_pkg_t structures

Initialize the transaction. @param handle the context handle @param flags flags of the transaction (like nodeps, etc; see alpm_transflag_t) @return 0 on success, -1 on error (pm_errno is set accordingly)

Interrupt a transaction. @param handle the context handle @return 0 on success, -1 on error (pm_errno is set accordingly)

Prepare a transaction. @param handle the context handle @param data the address of an alpm_list where a list of alpm_depmissing_t objects is dumped (conflicting packages) @return 0 on success, -1 on error (pm_errno is set accordingly)

Release a transaction. @param handle the context handle @return 0 on success, -1 on error (pm_errno is set accordingly)

Remove the database lock file @param handle the context handle @return 0 on success, -1 on error

Unregister all package databases. Databases can not be unregistered while there is an active transaction.

Get the version of library. @return the library version, e.g. “6.0.4”

Type Definitions

Local package or package file backup entry

Type of download progress callbacks. @param ctx user-provided context @param filename the name of the file being downloaded @param event the event type @param data the event data of type alpm_download_event_*_t

Event callback.

A callback for downloading files @param ctx user-provided context @param url the URL of the file to be downloaded @param localpath the directory to which the file should be downloaded @param force whether to force an update, even if the file is the same @return 0 on success, 1 if the file exists and is identical, -1 on error.

The callback type for logging.

Progress callback

Question callback.

A conflict that has occurred between two packages.

A database.

The usage level of a database.

The basic dependency type.

Missing dependency.

Context struct for when a download completes.

Context struct for when a download starts.

Context struct for when a download progresses.

Context struct for when a download retries.

An event that may represent any event.

A database is missing.

A pre/post transaction hook was ran.

pre/post transaction hooks are to be ran.

An optional dependency was removed.

A package operation event occurred.

A pacnew file was created.

A pacsave file was created.

Packages downloading about to start.

A package was downloaded.

A scriptlet was ran.

Events. This is a union passed to the callback that allows the frontend to know which type of event was triggered (via type). It is then possible to typecast the pointer to the right structure, or use the union field, in order to access event-specific data.

File in a package

File conflict.

Package filelist container

Package group

The libalpm context handle.

Logging Levels

A PGP key

A package.

Method used to validate a package.

A question that can represent any other question.

Should a conflicting package be removed?

Should a corrupted package be deleted?

Should a key be imported?

Should target in ignorepkg be installed anyway?

Should unresolvable targets be removed from the transaction?

Should a package be replaced?

Questions. This is an union passed to the callback that allows the frontend to know which type of question was triggered (via type). It is then possible to typecast the pointer to the right structure, or use the union field, in order to access question-specific data.

Type of question. Unlike the events or progress enumerations, this enum has bitmask values so a frontend can use a bitmask map to supply preselected answers to the different types of questions.

PGP signature verification options

Signature list. Contains the number of signatures found and a pointer to an array of results. The array is of size count.

Signature result. Contains the key, status, and validity of a given signature.

The time type used by libalpm. Represents a unix time stamp @ingroup libalpm_misc

Transaction structure used internally by libalpm @ingroup libalpm_trans

Transaction flags

Unions

Events. This is a union passed to the callback that allows the frontend to know which type of event was triggered (via type). It is then possible to typecast the pointer to the right structure, or use the union field, in order to access event-specific data.

Questions. This is an union passed to the callback that allows the frontend to know which type of question was triggered (via type). It is then possible to typecast the pointer to the right structure, or use the union field, in order to access question-specific data.
