digitalmars.D - Dumping the contents of memory to a file
I was wondering if there was a way to dump the contents of the heap to a file. If the heap is guaranteed to be in one contiguous chunk, then all I would need is: - The start address of the heap - The current size of the heap If it is not in one contiguous chunk, then it might be a little more complicated. I'm okay with writing out way more data than needed, I don't need to compress anything or remove unused but allocated space. This is for a debugging tool, and so can be a little hacky. Is this feasible? Does the request make sense? Thanks!

If you want to program continue to run, then it becomes interesting. Are there more threads? You probably want to stop them, so nobody modifies the heap while you dump it. Apart from that, just look at how to do it in C. https://stackoverflow.com/questions/3565232/how-to-programmatically-get-the-address-of-the-heap-on-linux
