read the contents (C struct) of the memory

I need to read the contents of the memory in a Qt application. The contents are loaded by a C module (header file in my application, and part of legacy code) which reads a long formatted text file and creates a big data structure (Struct) inside the memory. I just need to read that Struct in Qt and put the contents in appropriate variables/containers and use them in GraphScence for visualization. Any sample code will be highly appreciated.

Qt is nothing like C++ so what is your problem.
