ProxyObject & error verification in D-Bus Method Calls

[sumeet.pawnikar at wipro.com]

Hi All,
 
I have written the D-Bus Server Side Code.
I have implemented the D-Bus methods and signals.
 
In Any D-Bus method call, I have to provide the first argument of that
method call is ProxyObject.
Also, one of the argument is GError error.
 
But, in the defination ( implementation ) of this D-Bus method call, I
am not using these two parameters : ProxyObject , error.
 
gboolean D-Bus_method_call ( DBusGPRoxy* PRoxyObject, guchar* RetStatus,
GError* error )
{
 
}
 
 
When I make using warning flags set, 
it gives the below warnings which is related to the "D-Bus Proxy Object
and error " at some locations, 
 
 
file.c: In function 'D-Bus method call":
file.c:22: warning: unused parameter 'proxyObj'
file.c:22: warning: unused parameter 'error'

 
Because thesse are the D-Bus method calls parameters and these method
calls require this "proxy object".
 
Should we remove these warnings ?
 
I have one fix for this as below : 
 
As soon as I entered the D-Bus method call, I will check ProxyObject
using below api :
gboolean D-Bus_method_call ( DBusGPRoxy* PRoxyObject, guchar* RetStatus,
GError* error )
{
g_return_val_if_fail (DBUS_IS_G_PROXY (ProxyObject), FALSE);    // FALSE
is return value of D-Bus method
dbus_error_init (error);
if (dbus_error_is_set (error))     // checking the error is set or not

{
        printf ("%s\n", error);
        dbus_error_free (error);
}
return TRUE; 
}
Pls, correct me if I am wrong anywhere ? Or let me know this approach is
correct.
 
 
Thanks and Regards,
Sumeet Pawnikar
