## Description

This section contains code for working with the org.freedesktop.UDisks2.Manager D-Bus interface in C.

## Details

### UDisksManager

    typedef struct _UDisksManager UDisksManager;

Abstract interface type for the D-Bus interface org.freedesktop.UDisks2.Manager.

### struct UDisksManagerIface

    struct UDisksManagerIface {
      GTypeInterface parent_iface;

      gboolean (*handle_loop_setup) (
        UDisksManager *object,
        GDBusMethodInvocation *invocation,
        GUnixFDList *fd_list,
        GVariant *arg_fd,
        GVariant *arg_options);

      const gchar * (*get_version) (UDisksManager *object);

      gboolean (*handle_mdraid_create) (
        UDisksManager *object,
        GDBusMethodInvocation *invocation,
        const gchar *const *arg_blocks,
        const gchar *arg_level,
        const gchar *arg_name,
        guint64 arg_chunk,
        GVariant *arg_options);
    };

Virtual table for the D-Bus interface org.freedesktop.UDisks2.Manager.

GTypeInterface `parent_iface`; | The parent interface.
`handle_loop_setup` () | Handler for the "handle-loop-setup" signal.
`get_version` () | Getter for the "version" property.
`handle_mdraid_create` () | Handler for the "handle-mdraid-create" signal.

### udisks_manager_interface_info ()

    GDBusInterfaceInfo * udisks_manager_interface_info      (void);

Gets a machine-readable description of the org.freedesktop.UDisks2.Manager D-Bus interface.

Returns : | A GDBusInterfaceInfo. Do not free. [transfer none]

### udisks_manager_override_properties ()

    guint               udisks_manager_override_properties  (GObjectClass *klass,
                                                             guint property_id_begin);

Overrides all GObject properties in the UDisksManager interface for a concrete class. The properties are overridden in the order they are defined.

`klass` : | The class structure for a GObject-derived class.
`property_id_begin` : | The property id to assign to the first overridden property.
Returns : | The last property id.

### udisks_manager_get_version ()

    const gchar *       udisks_manager_get_version          (UDisksManager *object);

Gets the value of the "Version" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

### Warning

The returned value is only valid until the property changes so on the client-side it is only safe to use this function on the thread where `object` was constructed. Use `udisks_manager_dup_version()` if on another thread.

`object` : | A UDisksManager.
Returns : | The property value or `NULL` if the property is not set. Do not free the returned value, it belongs to `object`. [transfer none]

### udisks_manager_dup_version ()

    gchar *             udisks_manager_dup_version          (UDisksManager *object);

Gets a copy of the "Version" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

`object` : | A UDisksManager.
Returns : | The property value or `NULL` if the property is not set. The returned value should be freed with `g_free()`. [transfer full]

### udisks_manager_set_version ()

    void                udisks_manager_set_version          (UDisksManager *object,
                                                             const gchar *value);

Sets the "Version" D-Bus property to `value`.

Since this D-Bus property is not writable, it is only meaningful to use this function on the service-side.

`object` : | A UDisksManager.
`value` : | The value to set.

### udisks_manager_call_loop_setup ()

    void                udisks_manager_call_loop_setup      (UDisksManager *proxy,
                                                             GVariant *arg_fd,
                                                             GVariant *arg_options,
                                                             GUnixFDList *fd_list,
                                                             GCancellable *cancellable,
                                                             GAsyncReadyCallback callback,
                                                             gpointer user_data);

Asynchronously invokes the `LoopSetup()` D-Bus method on `proxy`.

### udisks_manager_skeleton_new ()

    UDisksManager *     udisks_manager_skeleton_new         (void);

Creates a skeleton object for the D-Bus interface org.freedesktop.UDisks2.Manager.

Returns : | The skeleton object. [transfer full][type UDisksManagerSkeleton]

## Property Details

### The `"version"` property

      "version"                  gchar*                : Read / Write

Represents the D-Bus property "Version".

Since the D-Bus property for this GObject property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.

Default value: NULL

## Signal Details

### The `"handle-loop-setup"` signal

    gboolean            user_function                      (UDisksManager         *object,
                                                            GDBusMethodInvocation *invocation,
                                                            GUnixFDList           *fd_list,
                                                            GVariant              *arg_fd,
                                                            GVariant              *arg_options,
                                                            gpointer               user_data)        : Run Last

Signal emitted when a remote caller is invoking the `LoopSetup()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `udisks_manager_complete_loop_setup()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

`object` : | A UDisksManager.
`invocation` : | A GDBusMethodInvocation.
`fd_list` : | A GUnixFDList or `NULL`. [allow-none]
`arg_fd` : | Argument passed by remote caller.
`arg_options` : | Argument passed by remote caller.
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

### The `"handle-mdraid-create"` signal

    gboolean            user_function                      (UDisksManager         *object,
                                                            GDBusMethodInvocation *invocation,
                                                            GStrv                  arg_blocks,
                                                            gchar                 *arg_level,
                                                            gchar                 *arg_name,
                                                            guint64                arg_chunk,
                                                            GVariant              *arg_options,
                                                            gpointer               user_data)        : Run Last

Signal emitted when a remote caller is invoking the `MDRaidCreate()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `udisks_manager_complete_mdraid_create()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

`object` : | A UDisksManager.
`invocation` : | A GDBusMethodInvocation.
`arg_blocks` : | Argument passed by remote caller.
`arg_level` : | Argument passed by remote caller.
`arg_name` : | Argument passed by remote caller.
`arg_chunk` : | Argument passed by remote caller.
`arg_options` : | Argument passed by remote caller.
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.
