Loading an MIP solution

I'm having trouple loading an existing MIP solution into XPRESS using C++. The documentation for "load MIP solution" has the following example based on C:

 

XPRBprob expl2;double vals[] = {1.5, 1, 0, 4, 2.2};expl2 = XPRBnewprob("example2");if (XPRBloadmipsol(expl2, vals, 5, 0)!=0) printf("Loading the solution failed.\n");

Here, vals is an array (of size 5) that holds the MIP solution you want to feed in, and expl2 is the name of your problem.

 

This all seems fine, but I am implementing a similar system in C++, so I have written the following code:

 

XPRBprob expl2("example2");double vals[] = {1.5, 1, 0, 4, 2.2};if (XPRBloadmipsol(expl2, vals, 5, 0)!=0)        cout<<"Loading the solution failed.\n";

However, the XPRBloadmipsol statement does not work. Specifically, I get the following error when I compile:

 

error C2664: 'xbloadmipsol_prob' : cannot convert parameter 1 from 'class dashoptimization::XPRBprob' to 'struct Xbprob *'

This suggests that the paramters for the C++ version of this function are different to the C version. But I cannot find any documentation on this.

 

Could anyone offer any help?

 

Thanks
