Haven't been using callbacks for a while. I forgot how to obtain lp solution at a child node. I kind of remember the following:

1, obtain node lp by CPXgetcallbackinfo + CPX_CALLBACK_INFO_USER_PROBLEM
2, then use CPXgetx + node lp instance to get solution.

Did I miss anything? or is there a better way to do this?

Thanks!

Sorry for this spam. I came across the function CPXgetcallbacknodex. Now I remember I used it before. This should be the function I'm looking for. Bad memory :)
