Using Intel IPP to decompress a lossless JPEG

I am trying to decompress the following lossless JPEG bitstream (ITU 81):

It seems to have been generated by:

$ strings -n 20 intel_ipp_lossless.jpg 
4Intel(R) IPP JPEG encoder [5.3.497] - Aug 12 2008

I am having a hard time understanding how to use IPP:

https://software.seek.intel.com/performance-libraries
- -> Intel® Integrated Performance Primitives

When I look at the examples I cannot find anything related to JPEG decompression anymore.

Where/How can I use IPP JPEG decoder ?
