Hi
Iam new to dbus and i want to register object and service to dbus using c code.
I tried with some example code but none of them is registering the object and hence i cant call those methods remotely.
Can any one help me in this?
My server side code is as follows:

#include <dbus/dbus-glib.h>
#include <dbus/dbus-glib-bindings.h>
#include <time.h>
#include <string.h>
#include <stdio.h>
int hello_alarm_alarm_example_callapi(int a);
#include "hello_alarm.h"

typedef struct
{

DBusGConnection *bus;
} AppData;

/* Define new GObject structure
* HelloAlarm */
typedef struct
{
GObject parent;
/* Define a pointer to store
* appdata */
AppData *appdata;
} HelloAlarm;

/* Define HelloAlarm's class */
typedef struct
{
GObjectClass parent;

/* HelloAlarm's say_hello-method.
* This will be registered as a DBUS-method */
int (*alarm_example_callapi)(int a);
} HelloAlarmClass;

static void hello_alarm_class_init(HelloAlarmClass *klass)
{
/* Define implementation location of the
* say_hello-method */
klass->alarm_example_callapi =hello_alarm_alarm_example_callapi;
}
GType hello_alarm_get_type()
{
static GType type = 0;
/* If the type is already registered,
* return it, otherwise register the
* GTypeInfoStructure */
if(!type)
{
static const GTypeInfo info =
{
sizeof(HelloAlarmClass),
NULL, /* base_init */
NULL, /* base_finalize */
(GClassInitFunc)hello_alarm_class_init, /* class_init */
NULL, /* class_finalize */
NULL, /* class_data */
sizeof(HelloAlarm),
0, /* n_preallocs */
NULL, /* instance_init */
};

type = g_type_register_static(G_TYPE_OBJECT, "HelloAlarmType",
&info, 0);
}

return type;
}


static gboolean
register_service(DBusGConnection *bus, GObject *obj,
const DBusGObjectInfo *info,
gchar *name, gchar *path, GError **error)
{
DBusGProxy *system;
gboolean result;
guint request_name_result;
/* Install GObject's info so glib knows
* what kind of interface to present on
* D-BUS */

/* Register the object to D-BUS using
* given object path */

printf("Failed to acquire org.designfu.SampleService %s", error); */

/* Request a name for the service from D-BUS */
/*result = org_freedesktop_DBus_request_name(system,

result = org_freedesktop_DBus_request_name(system,
