warning: function is not a prototype

[dissectcode]

Hello - I have another warning coming from my code and I honestly don't know why it's complaining.

I have a simple file

#include header.h

void function1()
{
  does something;
}

void function2()
{
}

Notice that function2 is empty for now, but the compiler gives me "warning: function not a prototype" for line "void function2()". I didn't think there needs to be a prototype since its not being called before it(function1 doesn't call it)...is it a problem that it's empty ??

Thanks!

UPDATE: I put a "void" as the explicit parameter in function2 and it got rid of the warning. Does anyone know what the reasoning behing that is?

Sounds like a bogus warning. I compiled your example code using Visual Studio.NET 2008 and got no warnings or errors.

An empty function is OK in C++.
