Constructor

GioDBusProxynew_sync

since: 2.26

Declaration [src] 

GDBusProxy*
g_dbus_proxy_new_sync (
  GDBusConnection* connection,
  GDBusProxyFlags flags,
  GDBusInterfaceInfo* info,
  const gchar* name,
  const gchar* object_path,
  const gchar* interface_name,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Creates a proxy for accessing interface_name on the remote object at object_path owned by name at connection and synchronously loads D-Bus properties unless the G_DBUS_PROXY_FLAGS_DO_NOT_LOAD_PROPERTIES flag is used.

If the G_DBUS_PROXY_FLAGS_DO_NOT_CONNECT_SIGNALS flag is not set, also sets up match rules for signals. Connect to the GDBusProxy::g-signal signal to handle signals from the remote object.

If both G_DBUS_PROXY_FLAGS_DO_NOT_LOAD_PROPERTIES and G_DBUS_PROXY_FLAGS_DO_NOT_CONNECT_SIGNALS are set, this constructor is guaranteed to return immediately without blocking.

If name is a well-known name and the G_DBUS_PROXY_FLAGS_DO_NOT_AUTO_START and G_DBUS_PROXY_FLAGS_DO_NOT_AUTO_START_AT_CONSTRUCTION flags aren’t set and no name owner currently exists, the message bus will be requested to launch a name owner for the name.

This is a synchronous failable constructor. See g_dbus_proxy_new() and g_dbus_proxy_new_finish() for the asynchronous version.

GDBusProxy is used in this [example][gdbus-wellknown-proxy].

Parameters

connection

Type: GDBusConnection

A GDBusConnection.

The data is owned by the caller of the function.
flags

Type: GDBusProxyFlags

Flags used when constructing the proxy.

info

Type: GDBusInterfaceInfo

A GDBusInterfaceInfo specifying the minimal interface that proxy conforms to or NULL.

The argument can be NULL.
The data is owned by the caller of the function.
name

Type: const gchar*

A bus name (well-known or unique) or NULL if connection is not a message bus connection.

The argument can be NULL.
The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.
object_path

Type: const gchar*

An object path.

The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.
interface_name

Type: const gchar*

A D-Bus interface name.

The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.
cancellable

Type: GCancellable

A GCancellable or NULL.

The argument can be NULL.
The data is owned by the caller of the function.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will be left initialized to NULL by the constructor if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GDBusProxy

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

The caller of the function takes ownership of the data, and is responsible for freeing it.
