Ah, okay. This is precise what I did in BDB recently with the svn_fs_get_locks() API. It's callback-ish, and the callbacks were being driven from way deep in the our BDB table cursor-crawling code. To make the API usable to third-parties (who almost *always* want to do something FS-ish with the lock information they get), I now -- just inside the API, squirrel the lock information from the BDB layer away to a tempfile, then read the tempfile back to drive the public callback system. It's not lovely, it's not fast, but it saves API consumers from having to essentially do the same thing anyway. -- C.
