Enumerator

ALPM_TRANS_FLAG_NODEPS

Ignore dependency checks.

ALPM_TRANS_FLAG_FORCE

Ignore file conflicts and overwrite files.

Delete files even if they are tagged as backup.

ALPM_TRANS_FLAG_NODEPVERSION

Ignore version numbers when checking dependencies.

ALPM_TRANS_FLAG_CASCADE

Remove also any packages depending on a package being removed.

ALPM_TRANS_FLAG_RECURSE

Remove packages and their unneeded deps (not explicitly installed).

ALPM_TRANS_FLAG_DBONLY

Modify database but do not commit changes to the filesystem.

ALPM_TRANS_FLAG_ALLDEPS

Use ALPM_PKG_REASON_DEPEND when installing packages.

ALPM_TRANS_FLAG_DOWNLOADONLY

Only download packages and do not actually install.

ALPM_TRANS_FLAG_NOSCRIPTLET

Do not execute install scriptlets after installing.

Function Documentation

int alpm_trans_commit (alpm_handle_t * handle, alpm_list_t ** data)

Commit a transaction.

Parameters:

handle the context handle
data the address of an alpm_list where detailed description of an error can be dumped (i.e. list of conflicting files)

Returns:

0 on success, -1 on error (pm_errno is set accordingly)

alpm_list_t* alpm_trans_get_add (alpm_handle_t * handle)

Returns a list of packages added by the transaction.

Parameters:

handle the context handle

Returns:

a list of alpm_pkg_t structures

alpm_transflag_t alpm_trans_get_flags (alpm_handle_t * handle)

Returns the bitfield of flags for the current transaction.

Parameters:

handle the context handle

Returns:

the bitfield of transaction flags

alpm_list_t* alpm_trans_get_remove (alpm_handle_t * handle)

Returns the list of packages removed by the transaction.

Parameters:

handle the context handle

Returns:

a list of alpm_pkg_t structures

int alpm_trans_init (alpm_handle_t * handle, alpm_transflag_t flags)

Initialize the transaction.

Parameters:

handle the context handle
flags flags of the transaction (like nodeps, etc)

Returns:

0 on success, -1 on error (pm_errno is set accordingly)

int alpm_trans_interrupt (alpm_handle_t * handle)

Interrupt a transaction.

Parameters:

handle the context handle

Returns:

0 on success, -1 on error (pm_errno is set accordingly)

Note:

Safe to call from inside signal handlers.

int alpm_trans_prepare (alpm_handle_t * handle, alpm_list_t ** data)

Prepare a transaction.

Parameters:

handle the context handle
data the address of an alpm_list where a list of alpm_depmissing_t objects is dumped (conflicting packages)

Returns:

0 on success, -1 on error (pm_errno is set accordingly)

int alpm_trans_release (alpm_handle_t * handle)

Release a transaction.

Parameters:

handle the context handle

Returns:

0 on success, -1 on error (pm_errno is set accordingly)
