function without arguments warned as being without a prototype about orangec

[lionfaith]

Note that putting void for the arguments removes the warning. That is void empty_func(void) instead of void empty_func().

Hi @lionfaith!
I send a pull request to David, with the correction of this problem, take a look in pull #18

Hi Lionfaith,

yes that is expected, emptyfunc() is different from emptyfunc(void) in
the C language (because the former actually allows you to put any number
of arguments in the call whereas the latter allows you to put none).
The disparity between those is part of the reason for the warning.

In C++ that was changed so that the two prototypes are equivalent.

Bencz's change fixes the problem but I think it has unintended side
effects. It may not properly issue errors if the argument types don't
match the parameter types.

After some playing around with mingw32-cc I decided to leave the warning
but demote it to a 'trivial' warning so it won't show up unless you ask
for it.

I will have a new release within the next couple of days.

Hi David,
thanks for your nice answer with my mistake.

C is confusing and even experienced programmer makes the mistake as I could read on stackoverflow. I just tested the same code on this online compiler with Clang and Gcc. And here I could test with msvc. Apparently, none of them complains about empty_func().

Thanks to you @bencz for your quick response.
