> You do RAII in C by wrapping everything up in opaque structures allocated by dedicated allocators and freed either by dedicated freers or by APR-style pool destructors.

Right, roughly what I was thinking of. Thanks for the concrete pointers!

Except of course that there is no overriding need to use memory pools. You can also keep track of multiple allocations (possibly also with destructors) in some structure and free them all at one go when you are done. Freeing many allocations in one go rather than freeing each as soon as it is no longer needed might also be more efficient cache-wise.
