Hey Diego, as we just talked over the phone, here is the diff I had sitting in my stash to ask the pph cache to replace the next cache insert by the given pointer (while still reading what's in the stream).
To use it simply call pph_cache_replace_next_by(stream, your_new_pointer) and immediately after call pph_in_(whatever you want to read in and immediately replace the cache pointer value for). Cheers, Gab
