Create DofMap in C++

Question

How do I write the C++ counterpart for creating a dofmap, which in Python is done by:

dm = V.dofmap()

Answer 1

It's the exact same call, i.e., once you have a FunctionSpace defined in your c++ code, you simply retrieve the dofmap via

std::shared_ptr<const GenericDofMap> dofmap = V.dofmap();
