C++ 在一个参数中传递多个参数

Question

这听起来可能令人困惑，但您如何在一个 ARGUMENT 中传递多个 ARGUMENT。

我试过的是:

#define CALL(v, look, param, expect) v(param){look(expect);}

使用示例(不起作用):

void CALL(InitD3D, engine->InitD3D, (HWND hWnd, bool windowed), (hWnd, windowed))

// Which should give(i want it to):
// void InitD3D(HWND hWnd, bool windowed){engine->InitD3D(hWnd, windowed);}
// But it may give: InitD3D((HWND hWnd, bool windowed)){engine->InitD3D((hWnd, windowed));}
// Or something similar or not...

基本单词也是如此，我怎样才能在一个参数中传递多个参数，而不会搞砸......

谢谢

Answer 1

#define CALL(v, look, param, expect) v param {look expect;}

namespace foo {
  void bob(int x, int y) {}
}
CALL(void bob, foo::bob, (int x, int y), (x,y))

int main() {
  bob(7,2);
}

我建议不要使用这种技术。
