DBusConnection.callWithUnixFdListSync

glib.variant.Variant callWithUnixFdListSync(string busName,  string objectPath,  string interfaceName,  string methodName,  glib.variant.Variant parameters,  glib.variant_type.VariantType replyType,  gio.types.DBusCallFlags flags,  int  timeoutMsec,  gio.unix_fdlist.UnixFDList fdList,  out  gio.unix_fdlist.UnixFDList outFdList,  gio.cancellable.Cancellable cancellable =  null)

Like [gio.dbus_connection.DBusConnection.callSync] but also takes and returns #GUnixFDList objects. See [gio.dbus_connection.DBusConnection.callWithUnixFdList] and [gio.dbus_connection.DBusConnection.callWithUnixFdListFinish] for more details.

This method is only available on UNIX.

Parameters

`busName`	a unique or well-known bus name or null if connection is not a message bus connection
`objectPath`	path of remote object
`interfaceName`	D-Bus interface to invoke method on
`methodName`	the name of the method to invoke
`parameters`	a #GVariant tuple with parameters for the method or null if not passing parameters
`replyType`	the expected type of the reply, or null
`flags`	flags from the #GDBusCallFlags enumeration
`timeoutMsec`	the timeout in milliseconds, -1 to use the default timeout or `G_MAXINT` for no timeout
`fdList`	a #GUnixFDList or null
`outFdList`	return location for a #GUnixFDList or null
`cancellable`	a #GCancellable or null

Returns

null if error is set. Otherwise a non-floating

#GVariant tuple with return values. Free with [glib.variant.Variant.unref].

Throws

[ErrorWrap]
