Hi,
I have a look on zlib source code and see declarations like this:
void test_compress OF((Byte *compr, uLong comprLen,
Byte *uncompr, uLong uncomprLen));


What is OF ?

Thanks

Click to expand...

# ifdef STDC
# define OF(args) args
# else
# define OF(args) ()
# endif

There are some ancient C compilers (KR) that don't know anything about
prototypes.
