Can u explain: why in C we can have a reference to a pointer... but
not... a pointer to a reference.

Isn't it VOID pointer will be good for this, can point to anything or
nothing.

With Many Thanks.

What do you mean by "reference"? If you mean the word as
it's used in C++, C doesn't have that kind of "reference" at all.
Try comp.lang.c++ if that's the language you're using.

What do you mean by "this"?

even in C++ a void isn't a reference

Did you mean to say that a void* isn't a reference?

It is just a parameter that will be supplied by the member function
in C++ to call a function in C.
