I guess the short answer is that you "don't".

The long answer (reading the code) is that the void* corresponds to a 
private TypeArgument (if the type happened to be a linked type - none
of the examples provided appear to be), or a type defined within the
file that provides the field type in question.  For TYPE_ENUM, that
appears to be this (still reading the code):

typedef struct
  {
    char **kwds;
    int count;
    bool checkcase;
    bool checkunique;
  }
enumARG;

I'm looking at fty_enum.c for the last, and _nc_Make_Argument() in 
fld_def.c
