TDB(3) Linux Programmer's Manual TDB(3)


tdb - trivial database


A database similar to gdbm which allows multiple simultaneous writers.


This is a simple database API. It was inspired by the realisation that in Samba we have several ad-hoc bits of code that essentially implement small databases for sharing structures between parts of Samba. As I was about to add another I realised that a generic database module was called for to replace all the ad-hoc bits.

I based the interface on gdbm. I couldn't use gdbm as we need to be able to have multiple writers to the databases at one time.
