To make the multiple inheritance follows the standard c++ well, you should using virtual inheritance

HRESULT SelectItemAtPoint(POINT point)
{
    VARIANT varItem;
    IAccessible* pAcc;
    HRESULT hr = AccessibleObjectFromPoint(point, &pAcc, &varItem);
    if ((hr == S_OK))
    {
        hr = pAcc->accSelect((SELFLAG_TAKEFOCUS | SELFLAG_TAKESELECTION), varItem);
        VariantClear(&varItem);
        pAcc->Release();
    }
    return hr;

hr = pAcc->accSelect((SELFLAG_TAKEFOCUS | SELFLAG_TAKESELECTION), varItem);

Snake.Position += Snake.Velocity;

typedef vec2_t{
 int x;
 int y;

vec2 snakePosition;
vec2 snakeVelocity;

snakePosition.x += snakeVelocity.x;
snakePosition.y += snakeVelocity.y;

switch(pressedKey)

    case leftArrow:
        snakeVelocity = (vec2){-1,0};
        break;

        snakeVelocity = (vec2){1,0};

        break;

        snaeVelocity = (vec2){0,1};
        break;
}

Return Value
ATOM
If the function succeeds, the return value is the newly created atom.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
