A unique or well-known bus name or NULL if connection is not a message bus connection. [allow-none]
Path of remote object.
D-Bus interface to invoke method on.
The name of the method to invoke.
A GVariant tuple with parameters for the method or NULL if not passing parameters. [allow-none]
The expected type of the reply, or NULL. [allow-none]
Flags from the GDBusCallFlags enumeration.
The timeout in milliseconds, -1 to use the default timeout or G_MAXINT for no timeout.
A GCancellable or NULL. [allow-none]
NULL if error is set. Otherwise a GVariant tuple with return values. Free with g_variant_unref().
GException on failure.
Synchronously invokes the method_name method on the interface_name D-Bus interface on the remote object at object_path owned by bus_name. If connection is closed then the operation will fail with G_IO_ERROR_CLOSED. If cancellable is canceled, the operation will fail with G_IO_ERROR_CANCELLED. If parameters contains a value not compatible with the D-Bus protocol, the operation fails with G_IO_ERROR_INVALID_ARGUMENT. If reply_type is non-NULL then the reply will be checked for having this type and an error will be raised if it does not match. Said another way, if you give a reply_type then any non-NULL return value will be of this type. If the parameters GVariant is floating, it is consumed. Since 2.26
