## Types and Values

#define | PK_CLIENT_ERROR
#define | PK_CLIENT_TYPE_ERROR
enum | PkClientError

## Description

A GObject to use for accessing PackageKit asynchronously. If you're using PkClient to install, remove, or update packages, be prepared that the eula, gpg and trusted callbacks need to be rescheduled manually, as in http://www.packagekit.org/gtk-doc/introduction-ideas-transactions.html

## Functions

### pk_client_error_quark ()

    GQuark
    pk_client_error_quark (void);

An error quark for PkClientError.

#### Returns

an error quark.

Since: 0.5.2

### pk_client_new ()

    PkClient *
    pk_client_new (void);

PkClient is a nice GObject wrapper for PackageKit and makes writing frontends easy.

#### Returns

A new PkClient instance

Since: 0.5.2

### pk_client_generic_finish ()

    PkResults *
    pk_client_generic_finish (PkClient *client,
                              GAsyncResult *res,
                              GError **error);

Gets the result from the asynchronous function.

#### Parameters

client | a valid PkClient instance |
res | the GAsyncResult |
error | A GError or `NULL` |

#### Returns

the PkResults, or `NULL`. Free with `g_object_unref()`.
