While I'm not saying this is a good idea, you can combine a pool allocator with longjmp exceptions to get an approximation of unwinding. It requires that you are very careful about structuring your code, but I once wrote a whole web server this way: http://git.annexia.org/?p=rws.git;a=tree (using: http://git.annexia.org/?p=c2lib.git;a=tree ).

But sometimes it's not just memory. It can be files you need to close, or any other resource held.

That too can be queued up, with a list of functions to call to free those resources.

He was referring to a memory pool allocator. But regardless, good luck with the approach.

Pool allocators can easily deal with non-memory resources. The one I wrote in c2lib could.
