On Windows, you can do this:

void WaitForEnter()
{
    // if enter is already pressed, wait for
    // it to be released
    while (GetAsyncKeyState(VK_RETURN) & 0x8000) {}

    // wait for enter to be pressed
    while (!(GetAsyncKeyState(VK_RETURN) & 0x8000)) {}
}

I don't know the equivalent on Linux.
