i didnt implement it..But i searched for code that how may i do
that ..finally i m implementing the method as follow..and things
working properly..But i doubt whether i m correct or not..
NS_IMETHODIMP WebLock::GetWeakReference(nsIWeakReference **_retval)
{
if ( !_retval )
return NS_ERROR_NULL_POINTER;
*_retval = new nsWeakReference((nsSupportsWeakReference *)this);
nsresult status;
if ( !*_retval )
status = NS_ERROR_OUT_OF_MEMORY;
else
{
NS_ADDREF(*_retval);
status = NS_OK;
}
return status;
}
