Please can anybody tell me why am I getting this error in foll code? 
Your help is appreciated 


Code: 

DBusConnection *connection;
DBusError error;
LibHalContext *ctx;
dbus_error_init(&error);
if((connection = dbus_bus_get(DBUS_BUS_SYSTEM,&error)) == NULL)
{
printf("Error %s\n",error.message);
return 1;
}
if ( dbus_error_is_set(&error) )
{
printf("Unable to connect to DBus: %s\n",error.message);
return 1;
}
if((ctx = libhal_ctx_new())==NULL)
{
printf("Error %s\n",error.message);
return 1;
}
if ( !libhal_ctx_set_dbus_connection(ctx, connection) )
{
printf("Error %s\n",error.message);
return 1;
}
if ( !libhal_ctx_init(ctx, &error) )
