Hi, I've been reading about the FFI for getting Haskell to communicate with C code (C++ really). My intention is to handle most of the app - the GUI events in C++ and sending all of the processing logic in Haskell - including a database etc. Is the FFI the right tool for a situation where, while used extensively, Haskell is more or less there to take in data, like lists and spit out data like vectors etc back to C. I am looking to get a few test running where I can pass data in an out of Haskell like vectors of floats. Also, I noticed on the wiki example: Haskell start c_main I was a little confused by this. Does Haskell load up first because its a library? I couldn't figure out where it was being called in the C code or why Haskell loads first. Not a biggie just a bit of an impediment in understanding how it all works.
