C++ Pass Array as parameter to a function

Question

I have the following code that works correctly:

typedef void(__fastcall* _PackEndFunc)(int Buffer);
_PackEndFunc PackEndFunc;

    uintptr_t moduleBase = (uintptr_t)GetModuleHandle(L"processo.exe");

  PackEndFunc = (_PackEndFunc)(moduleBase + 0x8AA46C);

while (true)
    {

        if (GetAsyncKeyState(VK_NUMPAD3) & 1)
        {

            PackEndFunc(0x0A);

        }
        Sleep(10);
    }

I’d like to, instead of PackEndFunc(0x0A), pass a set of bytes or integers instead of a single value.

For example:

05 00 C1 01 18 E5 87

I am new to programming in c++ and as much as I study manipulation of arrays I cannot get this code right.
