Marshalling large amount of data from and to C
 
http://phyx.pastebin.com/WXGBr1bX shows the code I use to do this (it's autogenerated, so just looking at 1 block should be enough)
 
The tool is mine, so i can change the code it generates, but i would need to know how to do it better first.

What kind of marshalling are you referring to?
