## Functions

### udisks_block_zram_proxy_new ()

    void
    udisks_block_zram_proxy_new (GDBusConnection *connection,
                                 GDBusProxyFlags flags,
                                 const gchar *name,
                                 const gchar *object_path,
                                 GCancellable *cancellable,
                                 GAsyncReadyCallback callback,
                                 gpointer user_data);

Asynchronously creates a proxy for the D-Bus interface org.freedesktop.UDisks2.Block.ZRAM. See `g_dbus_proxy_new()` for more details.

When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from (see `g_main_context_push_thread_default()`). You can then call `udisks_block_zram_proxy_new_finish()` to get the result of the operation.

See `udisks_block_zram_proxy_new_sync()` for the synchronous, blocking version of this constructor.

#### Parameters

connection | A GDBusConnection. |
flags | Flags from the GDBusProxyFlags enumeration. |
name | A bus name (well-known or unique) or `NULL` if `connection` is not a message bus connection. | [nullable]
object_path | An object path. |
cancellable | A GCancellable or `NULL`. | [nullable]
callback | A GAsyncReadyCallback to call when the request is satisfied. |
user_data | User data to pass to `callback` . |

Since: 2.3.0

### udisks_block_zram_proxy_new_finish ()

                                        GError **error);

Finishes an operation started with `udisks_block_zram_proxy_new()`.

#### Parameters

res | The GAsyncResult obtained from the GAsyncReadyCallback passed to `udisks_block_zram_proxy_new()`. |
error | Return location for error or `NULL` |

#### Returns

The constructed proxy object or `NULL` if `error` is set.

See `udisks_block_zram_proxy_new_for_bus_sync()` for the synchronous, blocking version of this constructor.

#### Parameters

bus_type | A GBusType. |
flags | Flags from the GDBusProxyFlags enumeration. |

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

See `udisks_block_zram_call_activate_sync()` for the synchronous, blocking version of this method.

#### Parameters

proxy | A UDisksBlockZRAMProxy. |
arg_priority | Argument to pass with the method invocation. |
arg_options | Argument to pass with the method invocation. |
cancellable | A GCancellable or `NULL`. | [nullable]
callback | A GAsyncReadyCallback to call when the request is satisfied or `NULL`. |

### The `“num-reads”` property

      “num-reads”                guint64

Represents the D-Bus property "NumReads".

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.

## Signal Details

### The `“handle-activate”` signal

    gboolean
    user_function (UDisksBlockZRAM       *object,
                   GDBusMethodInvocation *invocation,
                   int                    arg_priority,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Activate()` 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_block_zram_complete_activate()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlockZRAM. |
invocation | A GDBusMethodInvocation. |
arg_priority | Argument passed by remote caller. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

`G_DBUS_METHOD_INVOCATION_HANDLED` or `TRUE` if the invocation was handled, `G_DBUS_METHOD_INVOCATION_UNHANDLED` or `FALSE` to let other signal handlers run.

### The `“handle-activate-labeled”` signal

    gboolean
    user_function (UDisksBlockZRAM       *object,
                   GDBusMethodInvocation *invocation,
                   int                    arg_priority,
                   char                  *arg_label,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `ActivateLabeled()` 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_block_zram_complete_activate_labeled()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlockZRAM. |
invocation | A GDBusMethodInvocation. |
arg_priority | Argument passed by remote caller. |
arg_label | Argument passed by remote caller. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

`G_DBUS_METHOD_INVOCATION_HANDLED` or `TRUE` if the invocation was handled, `G_DBUS_METHOD_INVOCATION_UNHANDLED` or `FALSE` to let other signal handlers run.

### The `“handle-deactivate”` signal

    gboolean
    user_function (UDisksBlockZRAM       *object,
                   GDBusMethodInvocation *invocation,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Deactivate()` 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_block_zram_complete_deactivate()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlockZRAM. |
invocation | A GDBusMethodInvocation. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

`G_DBUS_METHOD_INVOCATION_HANDLED` or `TRUE` if the invocation was handled, `G_DBUS_METHOD_INVOCATION_UNHANDLED` or `FALSE` to let other signal handlers run.

### The `“handle-refresh”` signal

    gboolean
    user_function (UDisksBlockZRAM       *object,
                   GDBusMethodInvocation *invocation,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Refresh()` 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_block_zram_complete_refresh()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlockZRAM. |
invocation | A GDBusMethodInvocation. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

`G_DBUS_METHOD_INVOCATION_HANDLED` or `TRUE` if the invocation was handled, `G_DBUS_METHOD_INVOCATION_UNHANDLED` or `FALSE` to let other signal handlers run.
