How to create a new GType using dbus-Glib?

Hi,

I'm trying to use the DBUS connection to communicate with the Marxbot medulla. But when I want to use the interface to send a "SetSpeed" event using the method "SendEventName", I need to create a new GTYPE "DBUS_TYPE_G_INIT16_ARRAY" which is an array of int16.

I found this function
"#define DBUS_TYPE_G_INIT16_ARRAY (dbus_g_type_get_collection("GArray",Int16))"
but it doesn't know the type Int16.

Note that I'm writing this code with C and I'm using the library "dbus-glib.h"

Please help me Smilie

NAME
dbus-send - Send a message to a message bus SYNOPSIS
dbus-send [--system | --session] [--dest=name] [--help] [--print-reply] [--type=type] destination_object_path message_name [contents...] DESCRIPTION
The dbus-send command is used to send a message to a D-Bus message bus. There are two standard message buses: o systemwide message bus - Disabled and not supported on Solaris, but installed on many systems as the "messagebus" init service. o per-user-login-session message bus - Enabled and supported on Solaris, and started each time a user logs in. The --system and --session options direct dbus-send to send messages to the system or session buses respectively. If neither is speci- fied, dbus-send sends to the session bus. Nearly all uses of dbus-send must provide the --dest argument which is the name of a connection on the bus to send the message to. If --dest is omitted, no destination is set. See http://www.freedesktop.org/software/dbus/ for more information. OPTIONS
The following options are supported: --dest=name Specify the name of the connection to receive the message. --help Show help information on standard output and exit. --print-reply Block for a reply to the message sent, and print any reply received. --session Send to the session message bus (this is the default). --system Send to the system message bus. The system bus is disabled and unsupported on Solaris. --type=type Specify "method_call" or "signal" (defaults to "signal"). OPERANDS
The following operands are supported: destination_object_path The object path of the message to send must always be specified. message_name The name of the message to send must always be specified. contents Following arguments, if any, are the message contents (message arguments). These are given as a type name, a colon, and then the value of the argument. The possible type names are: string, int32, uint32, double, byte, bool- ean. (D-Bus supports more types than these, but dbus-send currently does not.) EXAMPLES

EXIT STATUS
The following exit values are returned: 0 Application exited successfully >0 Application exited with failure FILES
