[Vol-users] Searching a Process's Memory

Hi all, I'm thinking I might have a fundamental misunderstanding here, so I'm hoping someone can help me out. I'm looking for remnants of a data structure in the memory of a specific process. Originally, the data would have been on a heap. I notice that in '/volatility/plugins/overlays/windows/windows.py' there is a function named: search_process_memory I thought this would do the trick, but examining the code I notice that it searches each of the VADs. Which leads me to my question: would data that was originally on a heap, but is no longer needed by the process still be in the VAD? That is, should I be able to find it using this method? If not, "where" is the data now? And is there a way of searching wherever that "where" is? I hope that makes sense! Bridgey
