How do I get the refresh rate of the monitor using GetCloneRefreshRates ？

[xqin01]

Display_Config data;

data.uidMonitorPrimary = 4096;

m_pCUIExternal8->GetCloneRefreshRates(sizeof(Display_Config), (BYTE*)&data, MAX_REFRESH_RATE, (BYTE*)&rate, (BYTE*)&rate2, &dwExtraErrorCode);

4096 is obtained using EmemActiveDevices.

used this method,the parameters are passed in correctly?If not, how do you pass the value.

I hope the expert will give me a suggestion.
