Why compile error in SetArgReferee

[jeromy]

Hi all,

I've encounter an error in using SetArgReferee, any
suggestions?

Thanks in advance!

std::vector<IFilter::QueryResult> result;
//IFilter::QueryResult r;
//r.t = IFilter::SERVICE_SVC;
//result.push_back(r);
EXPECT_CALL(m_filter,
QueryDownlinkRequired(_,_)).Times(1).WillOnce(SetArgReferee<1>(result));

From the compiler output it looks like the second argument to your QueryDownlinkRequired() function is a pointer, not a reference. If that's true, then you want to be using SetArgPointee() rather than SetArgReferee(). The latter is for when the argument is a reference.
