How can I implement opaque (abstract) data types in C? What's the difference between these two..

Answer / pankaj

Abstract data type in C can be implemented using structures :
struct abstract;
typedef struct abstract abstract_type;

Note that this didn't define the struct abstract fully, only an opaque struct. sizeof() can be used on it. Memory can be allocated by using some macros and typecasted into this type.
