It sounded like you use/have used C/C++.
The fact it doesn't have higher level abstraction should be it's benefit.
You customize your own abstraction to your needs.
We needed a library that could generically read in the fields from raw datafiles,
MYSQL, Oracle, and have a very successful system running now.
NULLS are accounted for.  It's written in C, and is very easy to use.
