C Handles - How to work with them?

I have in some documentation for a Dreamweaver plugin that I am doing that says the following:

void ** connectionData p>

• The connectionData argument is to process the data that the agent wants Dreamweaver to pass by when invoking other API functions.

I have no other information than a guide on connectionData. Thinking literally, I realized that the descriptor refers to a common descriptor, however I can not find documentation on working with common handles with respect to C.

HANDLE h = connectionData;

It will compile in my code. How exactly do I get “secrets” inside this data structure / can someone explain how the general handles for working C work?
