You can't, matlab does not understand C structures. You'll have to convert your structure to a matlab structure (which is a very different beast). See mxcreatestructarray and mxsetfield to create matlab structs.

Yes, you need to write code to copy each field one at a time.

Unless all the fields are the same type, I don't see any other way but to copy each field one by one I'm afraid.
