A couple of comments, mostly minor:

There are a couple of paste-o's where the arg type in iBase_EntitySet, 
but the arg name is ent*.

There's a comment at the top of the file that suggests that some 
functions will take either an entity or a set in the same argument slot, 
with an additional arg indicating which it is.  That doesn't show up 
anywhere in the file (which is good, because compilers would puke on 
that), but the comment should be removed.

Otherwise --- and with the caveat that I've not tried to implement or 
use it --- this looks reasonable enough to me as far as it goes.  Isn't 
it still missing some stuff about returning iterators instead of sets on 
request?
