How to use cv::imencode on IplImage?

I have an image saved in a variable fo type IplImage like this:

IplImage* fIplImageHeader;
fIplImageHeader = cvCreateImageHeader(cvSize(width, height), 8, 3);
fIplImageHeader->imageData = (char*) memblock;

How can I use the cv::imencode function on that image?

cv:imencode looks like this:

bool imencode(const string& ext, const Mat& img, vector<uchar>& buf, const vector<int>& params=vector<int>())

So obviously I need to convert IplImage to const Mat somehow but I cannot find how to do that in the documentation.

What should I do?

This does not work of course:

cv::imencode("JPG", fIplImageHeader, fIplImageHeader);
