## Implemented Interfaces

UDisksClient implements GInitable and GAsyncInitable.

## Description

UDisksClient is used for accessing the UDisks service from a client program.

## Functions

### UDISKS_CHECK_VERSION()

    #define             UDISKS_CHECK_VERSION(major,minor,micro)

Macro to check against the version of the libudisks2 library that is being compiled against.

#### Parameters

major | The major version to check for. |
minor | the minor version to check for. |
micro | The micro version to check for. |

#### Returns

`TRUE` if the version of the libudisks2 header files is the same as or newer than the passed in version.

### udisks_client_new ()

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

Asynchronously gets a UDisksClient. When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from.

#### Parameters

cancellable | A GCancellable or `NULL`. |
callback | Function that will be called when the result is ready. |
user_data | Data to pass to `callback` . |

### udisks_client_new_finish ()

    UDisksClient *
    udisks_client_new_finish (GAsyncResult *res,
                              GError **error);

Finishes an operation started with `udisks_client_new()`.

#### Parameters

res | A GAsyncResult. |
error | Return location for error or `NULL`. |

#### Returns

A UDisksClient or `NULL` if `error` is set. Free with `g_object_unref()` when done with it.

### udisks_client_new_for_connection ()

    void
    udisks_client_new_for_connection (GDBusConnection *connection,
                                      GCancellable *cancellable,
                                      GAsyncReadyCallback callback,
                                      gpointer user_data);

Like `udisks_client_new()` but takes a GDBusConnection which will be used when connecting to the UDisks daemon over D-Bus. This is useful for unit tests which may want to use GTestDBus to create a D-Bus daemon on the session bus.

#### Parameters

connection | a GDBusConnection. If `NULL`, a system bus connection will be used. | [nullable]
cancellable | A GCancellable or `NULL`. |
callback | Function that will be called when the result is ready. |
user_data | Data to pass to `callback` . |

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

Synchronously gets a UDisksClient for the local system.

#### Parameters

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

#### Returns

A UDisksClient or `NULL` if `error` is set. Free with `g_object_unref()` when done with it.

### udisks_client_get_object ()

    UDisksObject *
    udisks_client_get_object (UDisksClient *client,
                              const gchar *object_path);

Convenience function for looking up an UDisksObject for `object_path` .

#### Parameters

client | A UDisksClient. |
object_path | Object path. |

#### Returns

A UDisksObject corresponding to `object_path` or `NULL` if not found. The returned object must be freed with `g_object_unref()`.

[transfer full]

### udisks_client_peek_object ()

    UDisksObject *
    udisks_client_peek_object (UDisksClient *client,
                               const gchar *object_path);

Like `udisks_client_get_object()` but doesn't increase the reference count on the returned UDisksObject.

The returned object is only valid until removed so it is only safe to use this function on the thread where `client` was constructed. Use `udisks_client_get_object()` if on another thread.

#### Parameters

client | A UDisksClient. |
object_path | Object path. |

#### Returns

A UDisksObject corresponding to `object_path` or `NULL` if not found.

    udisks_client_get_object_manager (UDisksClient *client);

Gets the GDBusObjectManager used by `client` .

#### Parameters

client | A UDisksClient. |

#### Returns

A GDBusObjectManager. Do not free, the instance is owned by `client` .

[transfer none]

### udisks_client_get_manager ()

    UDisksManager *
    udisks_client_get_manager (UDisksClient *client);

Gets the UDisksManager interface on the well-known `/org/freedesktop/UDisks2/Manager` object.

#### Parameters

client | A UDisksClient. |

#### Returns

A UDisksManager or `NULL` if the udisksd daemon is not currently running. Do not free, the instance is owned by `client` .

[transfer none]

### udisks_client_settle ()

    void
    udisks_client_settle (UDisksClient *client);

Blocks until all pending D-Bus messages have been delivered. Also emits the (rate-limited) “changed” signal if changes are currently pending.

This is useful in two situations: 1. when using synchronous method calls since e.g. D-Bus signals received while waiting for the reply are queued up and dispatched after the synchronous call ends; and

1. when using asynchronous calls where the return value references a newly created object (such as the Manager.LoopSetup() method).

#### Parameters

client | A UDisksClient. |

### udisks_client_queue_changed ()

    void
    udisks_client_queue_changed (UDisksClient *client);

Queues up a “changed” signal and rate-limit it. See the documentation for the “changed” property for more information.

#### Parameters

client | A UDisksClient. |

Since: 2.1

Gets the RAID device (e.g. `/dev/md0`) for `raid` .

In the case of a split-brain syndrome, it is undefined which RAID device is returned. For example this can happen if `/dev/sda` and `/dev/sdb` are components of a two-disk RAID-1 and `/dev/md0` and `/dev/md1` are two degraded arrays, each one using exactly one of the two devices. Use `udisks_client_get_all_blocks_for_mdraid()` to get all RAID devices.

#### Parameters

raid | A UDisksMDRaid. |

#### Returns

A UDisksBlock or `NULL` if no RAID device is running.

## Types and Values

### UDISKS_MAJOR_VERSION

    #define UDISKS_MAJOR_VERSION 2

The major version of the libudisks2 header files.

### UDISKS_MINOR_VERSION

    #define UDISKS_MINOR_VERSION 10

The minor version of the libudisks2 header files.

### UDISKS_MICRO_VERSION

    #define UDISKS_MICRO_VERSION 2

The micro version of the libudisks2 header files.

### UDisksClient

    typedef struct _UDisksClient UDisksClient;

The UDisksClient structure contains only private data and should only be accessed using the provided API.

### UDisksPartitionTypeInfo

    typedef struct {
      const gchar                  *table_type;
      const gchar                  *table_subtype;
      const gchar                  *type;
      UDisksPartitionTypeInfoFlags  flags;
    } UDisksPartitionTypeInfo;

Detailed information about a partition type.

`table_subtype` is used to break the set of partition types for `table_type` into a logical subsets. It is typically only used in user interfaces where the partition type is selected.

This struct may grow in the future without it being considered an ABI break.

#### Members

const gchar *`table_type`; | A partition table type e.g. 'dos' or 'gpt' |
const gchar *`table_subtype`; | A partition table sub-type. |
const gchar *`type`; | A partition type. |
UDisksPartitionTypeInfoFlags `flags`; | Flags from the UDisksPartitionTypeInfoFlags enumeration. |

### enum UDisksPartitionTypeInfoFlags

Flags describing a partition type.

#### Members

UDISKS_PARTITION_TYPE_INFO_FLAGS_NONE | No flags set. |
UDISKS_PARTITION_TYPE_INFO_FLAGS_SWAP | Partition type is used for swap. |
UDISKS_PARTITION_TYPE_INFO_FLAGS_RAID | Partition type is used for RAID/LVM or similar. |
UDISKS_PARTITION_TYPE_INFO_FLAGS_HIDDEN | Partition type indicates the partition is hidden (e.g. 'dos' type 0x1b "Hidden W95 FAT32"). Note that this is not the same as user-toggleable attributes/flags for a partition. |
UDISKS_PARTITION_TYPE_INFO_FLAGS_CREATE_ONLY | Partition type can only be used when creating a partition and e.g. should not be selectable in a "change partition type" user interface (e.g. 'dos' type 0x05, 0x0f and 0x85 for extended partitions). |
UDISKS_PARTITION_TYPE_INFO_FLAGS_SYSTEM | Partition type indicates the partition is part of the system / bootloader (e.g. 'dos' types 0xee, 0xff, 'gpt' types for 'EFI System partition' and 'BIOS Boot partition'). |

## Property Details

### The `“bus-connection”` property

      “bus-connection”           GDBusConnection *

The GDBusConnection used to create the “object-manager”, or `NULL` if one wasn't specified during construction of the UDisksClient (in which case a system bus connection is used).

Owner: UDisksClient

Flags: Read / Write / Construct Only

Since: 2.9.0

### The `“manager”` property

      “manager”                  UDisksManager *

The UDisksManager interface on the well-known `/org/freedesktop/UDisks2/Manager` object

Owner: UDisksClient

Flags: Read

### The `“object-manager”` property

      “object-manager”           GDBusObjectManager *

The GDBusObjectManager used by the UDisksClient instance.

Owner: UDisksClient

Flags: Read

## Signal Details

### The `“changed”` signal

    void
    user_function (UDisksClient *client,
                   gpointer      user_data)

This signal is emitted either when an object or interface is added or removed a when property has changed. Additionally, multiple received signals are coalesced into a single signal that is rate-limited to fire at most every 100ms.

Note that calling `udisks_client_settle()` will cause this signal to fire if any changes are outstanding.

For greater detail, connect to the “object-added”, “object-removed”, “interface-added”, “interface-removed”, “interface-proxy-properties-changed” and signals on the “object-manager” object.

#### Parameters

client | A UDisksClient. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last
