Question

Alright, I’m pretty sure that this has been discussed before in some way or another, but I’m apparently too stupid to find it.

First: I’m NOT looking for va_list and the other macros.
What I am looking for is something like the main-function parameters.

The default prototype, as all of you know is:

int main(int argc, char *argv[]);

Now, I want something similar for my program, but don’t know how exactly.

Let’s assume we have this function:

void Function(int argc, unsigned short *args[]) {
    for(int i = 0; i < argc; ++i) printf("%hu ", args[i]);
}

And I want something like this function call:

Function(5, 1, 2, 3, 4, 5);

Would that work?
Because I don’t want the ‘cluttering’ of va_list, nor do I want to create:

void AnotherFunction() {
    unsigned short Args[] = { 1, 2, 3, 4, 5 };
    Function(5, Args);
}

Simply because in that case I would only need a simple pointer.
Could someone please point me in the right direction? Thank you very much.

Edit:
Thank you everyone for your valuable input. I’ll settle for ‘Doesn’t work with standard C/C++ for now and look for a different approach to my problem.

Again, thank you very much.

Answer 1

A g++ specific solution:

const size_t MAX_ARGS = 42;

void Function(int argc, const unsigned short (&args)[MAX_ARGS])
{
}

int main()
{
    Function(5, {1,2,3,4,5});
}

If you don’t actually need the argc parameter, you can write a template:

template<size_t N>
void Function(const unsigned short(&args)[N])
{
    // use N
}

This works in C++03. The array needs to be const, or else you can’t pass a temporary initializer list like that. If you need to modify the elements inside the function, you’ll need to make a copy.
