Macro Definition Documentation

◆ Data_Get_Struct

#define Data_Get_Struct	(	mrb,
		obj,
		type,
		sval )

Value:

  *(void**)&sval = mrb_data_get_ptr(mrb, obj, type); \
} while (0)

◆ Data_Make_Struct

#define Data_Make_Struct	(	mrb,
		klass,
		strct,
		type,
		sval,
		data_obj )

Value:

  do { \
  (data_obj) = Data_Wrap_Struct(mrb,klass,type,NULL);\
  (sval) = (strct*)mrb_malloc(mrb, sizeof(strct));                     \
  { static const strct zero = { 0 }; *(sval) = zero; };\
  (data_obj)->data = (sval);\
} while (0)
