Can anyone tell how to use this function in Dev C++.

1) you are using Dev C++
2) you want to use rdtsc()
The first problem is easily fixed by upgrading to an actively maintained IDE. There's Code::Blocks, wxDev-C++, and Visual C++ Express.
What are trying to achieve by using rdtsc? Read this: http://en.wikipedia.org/wiki/Time_Stamp_Counter
