c++ std::nth_element-like sorting in IPP?

Does IPP contain a method for computing 'partially sorted' data? In particular, I'm looking for something comparable to the std::nth_element method in C++ that guarantees that data elements less than the element value at n reside at indices less than n, and those that are greater than the value at n reside at indices greater than n, but with no sorting guaranteed for indices i<n guaranteed (and, of course, none for i>n). Thanks in advance for your help.
