This code looks very, very wrong. It shouldn't be possible to convert this into clean C++ code, because it's not clean C code to start with!

First of all, you have two pointers that require some allocation, but you have two allocations assigned to the same variable, dl. Why do you have two allocations for dl? Where is the allocation for dr?

Second, both dl and dr are declared as pointers to some kind of struct. In clean C code, the implicit meaning of this is that these pointers are pointing to one or more structs of their respective types.

Apparently, you are allocating data structures that contain arrays of data structures along with additional information, without ever declaring that memory structure as data structure. That is completely inaccaptable, unclean code.

You should start by defining your actual data structures in C and clean up your original code. Then you can define arrays as std::vector or std::array, to safe yourself the effort of managing containers, and use new/delete to allocate your actual structs if you do need to allocate them dynamically - chances are, that once you get the container memory auto-managed by C++ classes, you can simply declare those structs on the stack.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
