## Implemented Interfaces

PolkitAuthority implements GInitable and GAsyncInitable.

## Description

PolkitAuthority is used for checking whether a given subject is authorized to perform a given action. Typically privileged system daemons or suid helpers will use this when handling requests from untrusted clients.

User sessions can register an authentication agent with the authority. This is used for requests from untrusted clients where system policy requires that the user needs to acknowledge (through proving he is the user or the administrator) a given action. See PolkitAgentListener and PolkitAgentSession for details.

## Functions

### polkit_authority_get_async ()

    void
    polkit_authority_get_async (GCancellable *cancellable,
                                GAsyncReadyCallback callback,
                                gpointer user_data);

Asynchronously gets a reference to the authority.

This is an asynchronous failable function. When the result is ready, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from and you can use `polkit_authority_get_finish()` to get the result. See `polkit_authority_get_sync()` for the synchronous version.

#### Parameters

cancellable | A GCancellable or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is satisfied. |
user_data | The data to pass to `callback` . |

### polkit_authority_get_finish ()

    PolkitAuthority *
    polkit_authority_get_finish (GAsyncResult *res,
                                 GError **error);

Finishes an operation started with `polkit_authority_get_async()`.

#### Parameters

res | A GAsyncResult obtained from the GAsyncReadyCallback passed to `polkit_authority_get_async()`. |
error | Return location for error or `NULL`. | [allow-none]

#### Returns

A PolkitAuthority. Free it with `g_object_unref()` when done with it.

    polkit_authority_get_sync (GCancellable *cancellable,
                               GError **error);

Synchronously gets a reference to the authority.

This is a synchronous failable function - the calling thread is blocked until a reply is received. See `polkit_authority_get_async()` for the asynchronous version.

#### Parameters

cancellable | A GCancellable or `NULL`. | [allow-none]
error | Return location for error or `NULL`. | [allow-none]

#### Returns

A PolkitAuthority. Free it with `g_object_unref()` when done with it.

#### Parameters

authority | A PolkitAuthority. |

#### Returns

The version string for the backend.

### polkit_authority_get_backend_features ()

    PolkitAuthorityFeatures
    polkit_authority_get_backend_features (PolkitAuthority *authority);

                                          const gchar *action_id,
                                          PolkitDetails *details,
                                          PolkitCheckAuthorizationFlags flags,

                                          gpointer user_data);

Asynchronously checks if `subject` is authorized to perform the action represented by `action_id` .

Note that `POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION` SHOULD be passed ONLY if the event that triggered the authorization check is stemming from an user action, e.g. the user pressing a button or attaching a device.

When the operation is finished, `callback` will be invoked in the

thread-default main loop of the thread you are calling this method

from. You can then call `polkit_authority_check_authorization_finish()` to get the result of the operation.

Known keys in `details` include `polkit.message` and `polkit.gettext_domain` that can be used to override the message shown to the user. See the documentation for the D-Bus method for more details.

If `details` is non-empty then the request will fail with POLKIT_ERROR_FAILED unless the process doing the check itsef is sufficiently authorized (e.g. running as uid 0).

#### Parameters

authority | A PolkitAuthority. |
subject | A PolkitSubject. |
action_id | The action to check for. |
details | Details about the action or `NULL`. | [allow-none]
flags | A set of PolkitCheckAuthorizationFlags. |
cancellable | A GCancellable or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is satisfied. |
user_data | The data to pass to `callback` . |

                                    GAsyncResult *res,
                                    GError **error);

Finishes checking if a subject is authorized for an action.

#### Parameters

authority | A PolkitAuthority. |
res | A GAsyncResult obtained from the callback. |
error | Return location for error or `NULL`. | [allow-none]

#### Returns

A PolkitAuthorizationResult or `NULL` if `error` is set. Free with `g_object_unref()`.

[transfer full]

### polkit_authority_check_authorization_sync ()

    PolkitAuthorizationResult *
    polkit_authority_check_authorization_sync
                                   (PolkitAuthority *authority,
                                    PolkitSubject *subject,
                                    const gchar *action_id,
                                    PolkitDetails *details,
                                    PolkitCheckAuthorizationFlags flags,
                                    GCancellable *cancellable,
                                    GError **error);

Checks if `subject` is authorized to perform the action represented by `action_id` .

Note that `POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION` SHOULD be passed ONLY if the event that triggered the authorization check is stemming from an user action, e.g. the user pressing a button or attaching a device.

Note the calling thread is blocked until a reply is received. You should therefore NEVER do this from a GUI thread or a daemon service thread when using the `POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION` flag. This is because it may potentially take minutes (or even hours) for the operation to complete because it involves waiting for the user to authenticate.

Known keys in `details` include `polkit.message` and `polkit.gettext_domain` that can be used to override the message shown to the user. See the documentation for the D-Bus method for more details.

#### Parameters

authority | A PolkitAuthority. |
subject | A PolkitSubject. |
action_id | The action to check for. |
details | Details about the action or `NULL`. | [allow-none]
flags | A set of PolkitCheckAuthorizationFlags. |
cancellable | A GCancellable or `NULL`. | [allow-none]
error | Return location for error or `NULL`. | [allow-none]

#### Returns

A PolkitAuthorizationResult or `NULL` if `error` is set. Free with `g_object_unref()`.

thread-default main loop of the thread you are calling this method

from. You can then call `polkit_authority_authentication_agent_response_finish()` to get the result of the operation.

#### Parameters

authority | A PolkitAuthority. |
cookie | The cookie passed to the authentication agent from the authority. |
identity | The identity that was authenticated. |
cancellable | A GCancellable or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is satisfied. |
