This is one of the main public interface classes. It is always constructed through operator overloading between expressions, constants, and variables. There are many 'friend' overloaded operators to do the constuction. The basic idea is to make the constraint look like a paper-model constraint in C++ code. Once constructed, it should be added to the model.
The snippet below is an overly simplistic example, but is ok for illustration.
MP_model aModel; // your model
MP_set I; // the set the constraint is defined over.
MP_variable x(I); // your variable
...
MP_constraint cons(I); // construct the right number of constraints.
cons = x <= 3;
// Assign in the semantic rep to it. aModel.add(cons); // add it to the model
There is quite a bit of C++ machinery going on there.
