twain driver

[JiY_54]

hi,
Got a data acquisition box with driver binary and source which is visual studio project. Liked to develop a twain driver SDK for it. I can control the box using set of DevControl export functions and capture data using a DevRecvData export function. I am totally new to Twain driver development.
where do i start from?.
any sample program?.
How these export functions translate into Twain entry points?.
Is Twain driver cross platform?.

Wouldn't' you like to use WIA instead?

what are advantages of WIA over twain?. Isn't twain used widespread?.
