GioDBusConnectioncall_with_unix_fd_list

since: 2.30

Declaration [src] 

void
g_dbus_connection_call_with_unix_fd_list (
  GDBusConnection* connection,
  const gchar* bus_name,
  const gchar* object_path,
  const gchar* interface_name,
  const gchar* method_name,
  GVariant* parameters,
  const GVariantType* reply_type,
  GDBusCallFlags flags,
  gint timeout_msec,
  GUnixFDList* fd_list,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Like g_dbus_connection_call() but also takes a GUnixFDList object.

The file descriptors normally correspond to G_VARIANT_TYPE_HANDLE values in the body of the message. For example, if a message contains two file descriptors, fd_list would have length 2, and g_variant_new_handle (0) and g_variant_new_handle (1) would appear somewhere in the body of the message (not necessarily in that order!) to represent the file descriptors at indexes 0 and 1 respectively.

When designing D-Bus APIs that are intended to be interoperable, please note that non-GDBus implementations of D-Bus can usually only access file descriptors if they are referenced in this way by a value of type G_VARIANT_TYPE_HANDLE in the body of the message.

This method is only available on UNIX.

Available since: 2.30

This method completes asynchronously. Use g_dbus_connection_call_with_unix_fd_list_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
