Why do you care? Just include that header and declare your pointer as

Of course. Otherwise how do you expect to call the function, if you
don't know how to set up one of its parameters? But it's not clear why
you feel you have to manually dig through header files just to declare a
pointer-to-function typedef.

or, since the symbols should be 'present' in the zipfile, so i dont
need to care (i am making a wild guess here)

I have no idea what you are talking about.

unzFile?

You go ahead and modify it, I guess. I don't understand this question,
either.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
