[Nemiver-list] Variables mixed up

[David S <dalidan domain hid>]

Hello,

I have a problem with debugging a small program that I built. The program variables seem to be mixed up. I have reviewed my code and I don't think it's my program's bug, however you may review the code if you wish.

Running Ubuntu 7.04.
Compiled with "gcc -ldb-4.5 -g -o database database.c".
Requires libdb-4.5.

The value exportkey.data should be the value of exportdata.data.
The program, when compiled, does what it's meant to.

Thankyou,
David S
