I am unclear as to how to pass information to and from my main code (C api) and the call back.  I looked through the examples and I don't see any callback examples that have information being printed to a txt file.   I am basically wanting to keep track of when(the time in seconds) an incumbent to a MIP is found and the value of the objective function. 

I need some help understanding how to get this to work.

Thanks for any help you can provide.
