A way for c++ code to access records from the UniVerse database?

Question

I know there is some kind of connection between .NET and UniVerse, by using UniObjects. But I believe that obligates use of .NET, and C# or VB.NET.

Also, I know by reading UniVerse manual that UniVerse can call C/C++ code from within UniVerse, but what I want is the other way around.

1. Can UniObjects be used for c++ project in .NET?
2. Can plain c++ (by plain i mean without using .NET platform) retrieve and store the data from and to UniVerse database?

Answer 1

Yes, although you have to hunt for it.

On the U2 DevZone site Rocket Software has just launched, there is an article about writing a PDO Driver for PHP access. This driver is written in C (iirc) and has all the source code supplied. It uses the U2 InterCall to interact with the U2 system (UniVerse & UniData). You should be able to use this as a way of making calls to the UniRPC process (this is what UniObjects calls).

You have to sign up to the site to access the article & source code, but sign up is free.

Answer 2

There is a library called icsdk. This will let you do just about anything that UniObj would let you do from a java or .NET framework but from C. I don't have the manuals with me to check right now, but if you can get the documentation from Rocket, you want to look up the ICS, or Intercall sections.
