   Flags/methods for returning states.

   The SWIG conversion methods, as ConvertPtr, return an integer
   that tells if the conversion was successful or not. And if not,
   an error code can be returned (see swigerrors.swg for the codes).

   Use the following macros/flags to set or process the returning
   states.

   In old versions of SWIG, code such as the following was usually written:

     if (SWIG_ConvertPtr(obj,vptr,ty.flags) != -1) {
       // success code
     } else {
       //fail code
     }

   Now you can be more explicit:

    int res = SWIG_ConvertPtr(obj,vptr,ty.flags);
    if (SWIG_IsOK(res)) {
      // success code
    } else {
      // fail code
    }

   which is the same really, but now you can also do

    Type *ptr;
    int res = SWIG_ConvertPtr(obj,(void **)(&ptr),ty.flags);
    if (SWIG_IsOK(res)) {
      // success code
      if (SWIG_IsNewObj(res) {
        ...
	delete *ptr;
      } else {
        ...
      }
    } else {
      // fail code
    }

   I.e., now SWIG_ConvertPtr can return new objects and you can
   identify the case and take care of the deallocation. Of course that
   also requires SWIG_ConvertPtr to return new result values, such as

      int SWIG_ConvertPtr(obj, ptr,...) {
        if (<obj is ok>) {
          if (<need new object>) {
            *ptr = <ptr to new allocated object>;
            return SWIG_NEWOBJ;
          } else {
            *ptr = <ptr to old object>;
            return SWIG_OLDOBJ;
          }
        } else {
          return SWIG_BADOBJ;
        }
      }

   Of course, returning the plain '0(success)/-1(fail)' still works, but you can be
   more explicit by returning SWIG_BADOBJ, SWIG_ERROR or any of the
   SWIG errors code.

   Finally, if the SWIG_CASTRANK_MODE is enabled, the result code
   allows to return the 'cast rank', for example, if you have this

       int food(double)
       int fooi(int);

   and you call

      food(1)   // cast rank '1'  (1 -> 1.0)
      fooi(1)   // cast rank '0'

   just use the SWIG_AddCast()/SWIG_CheckState()

/*
 * The following macros are used for providing the correct type of a
 * function pointer to the Ruby C API.
 * Starting with Ruby 2.7 (corresponding to RB_METHOD_DEFINITION_DECL being
 * defined) these macros act transparently due to Ruby's moving away from
 * ANYARGS and instead employing strict function signatures.
 *
 * Note: In case of C (not C++) the macros are transparent even before
 * Ruby 2.7 due to the fact that the Ruby C API used function declarators
 * with empty parentheses, which allows for an unspecified number of
 * arguments.
 *
 * PROTECTFUNC(f) is used for the function pointer argument of the Ruby
 * C API function rb_protect().
 *
 * VALUEFUNC(f) is used for the function pointer argument(s) of Ruby C API
 * functions like rb_define_method() and rb_define_singleton_method().
 *
 * VOIDFUNC(f) is used to typecast a C function that implements either
 * the "mark" or "free" stuff for a Ruby Data object, so that it can be
 * passed as an argument to Ruby C API functions like Data_Wrap_Struct()
 * and Data_Make_Struct().
 *
 * SWIG_RUBY_VOID_ANYARGS_FUNC(f) is used for the function pointer
 * argument(s) of Ruby C API functions like rb_define_virtual_variable().
