WTF is this?

extern unzFile ZEXPORT unzOpen OF((const char *path));


What is this mess? It's from the zlib source.

How the F should we know? Search the headers.

If I had to guess, the 'ZEXPORT' is a macro expanding into
some kind of compiler-specific nonsense like "__dllexport"
and 'OF' is a macro expanding into a function declaration
(or only the parameter list). 'unzFile' can be the return
value type, and 'unzOpen' is the actual name of the function
(if 'OF' is the function header without the name).

Run the source code thru the CPP and see what you get. gcc -E could do that as well.

Thanks a lot for the reply, it seems everything is what you
guessed.
