Need a file based database library

[Andreas Otto]

Hello,

I'm looking for a database library able to be used as a local application
storage.

The following requirements are necessary:

1. No TCP/IP or UDP interface
2. available as shared/static library
3. able to use multiple INDEX files to access DATA
-> the INDEX self have to be persistent
4. SQL not required
-> better without SQL interface
5. as simple as possible
6. source-code available
7. GPL/Apache or something equal as LICENSE
8. C/C++ interface
